FOREWORD. 


The  legislature  of  1921  appropriated  $200,000  for  an  investigation  of 
California's  water  resources  by  the  State  Department  of  Public  Works, 
Division  of  Engineering  and  Irrigation.  Accordingly,  an  engineering 
investigation  has  been  completed  and  a  report  transmitted  to  the  legis- 
lature on  January  1,  1923.  The  great  mass  of  data  collected  and  the 
complex  analyses  thereof  made  it  advisable  to  present  much  of  this 
information  in  separate  volumes.     Four  of  these  are  in  print,  entitled : 

Appendix  "A"  "Flow  in  California  Streams."  Bulletin  No.  5, 
State  Department  of  Public  Works. 

Appendix  "B"  "Irrigation  Requirements  of  California  Lands." 
Bulletin  No.  6,  State  Department  of  Public 
Works. 

Appendix  "C"  "Utilization  of  the  Water  Resources  of  Cali- 
fornia." Bulletin  No.  7,  State  Department  of 
Public  Works. 

Appendix  "D"  "Relation  of  Settlement  to  Irrigation  Develop- 
ment." Bulletin  No.  8,  State  Department  of 
Public  Works. 


Chapter  889  of  the  1921  Statutes,  which  authorized  this  investigation, 
provided  for  the  appointment  by  the  Governor  of  a  Consulting  Board 
to  advise  with  the  Department  in  their  endeavors.  The  following  were 
appointed  by  Governor  Stephens :

CHAPTER  I. 


MOUNTAINS. 

Three-fifths  of  the  land  expanse  of  California  is  a  rugged,  upturned, 
mountainous  region.  Although  comprising  an  area  of  100,000 
scpiare  miles,  upheaved  into  waves  of  earth  through  which  the 
jagged  rocks  jirotrude  in  peaks  that  attain  to  elevations  of  two  and 
three-ciuarter  miles,  they  are  but  wrinkles  and  creases  of  the  crust 
on  the  vast  surface  of  the  earth.  The  foldings  extend  in  a  general 
noithwesterly  and  southeasterly  direction,  with  the  highest  ridges 
forming  the  crests  of  the  state's  principal  mountain  ranges.  The 
innumerable  parallel  ridges  and  folds  of  lesser  elevation  give  breadth 
to  the  massive  mountain  structure  that  rises  out  of  the  sea  or  up  from 
I  he  valley  plain  and  covers  the  major  portion  of  this  state.  Folded 
into  parallel  corrugations,  the  bases  of  which  extend  half  the  width  of 
the  state,  these  mountains  are  deeply  cut  by  transverse  grooves  that 
shape  and  isolate  their  apexes  into  angular  peaks  and  rounded  domes. 

The  mountains  extend  from  the  ocean's  edge  to  the  state's  eastern 
boundary,  and  from  the  Oregon  line  to  the  Mexican  border.  So  vast 
is  this  mountainous  expanse  and  so  dense  is  the  distribution,  that  the 
flat  lands,  excepting  the  long  central  valley  of  the  Sacramento  and 
San  Joaquin,  occur  as  scattering  patches,  sprinkled  along  the  ocean 
margin  to  the  west  or  sparsely  apportioned  through  mountain  plateau, 
or  in  the  barren  desert  on  the  eastern  border  of  the  state.  Most  of 
the  mountainous  region  is  non-tillable,  being  deficient  in  soil  or  too 
steep  of  slope.  A  tenth  of  it,  however,  is  agricultural,  and  this  lies  in 
tht  mountain  valleys  and  on  the  sloping,  rolling  foothills  which  effect 
the  compromise  between  the  flat  valley  lands  and  the  labyrinth  of 
ridges  and  tangle  of  gorges,  constituting  the  highland  area  of  this 
state.  The  fretwork  of  wrinkles,  folds,  and  creases  that  compose  the 
relief  work  of  the  mountain  structure,  is  so  disposed  that  the  greater 
part  of  California's  jnountains  is  comprised  within  two  ranges.  These 
ranges  traverse  tlie  state  from  the  northwest  to  the  southeast  and  are 
approximately  parallel  to  each  other  and  to  the  state's  western  border. 

The  two  ranges  diverge  in  their  southerly  course  at  Mount  Shasta, 
within  forty  miles  of  the  Oregon  line.  In  their  deviation  from 
each  other  they  leave  between  their  bases  a  long,  flat  valley.  This 
valley,  one-quarter  the  breadth  of  the  state  and  half  its  length,  lies 
on  the  state's  median  line  and  includes  two-thirds  of  California's  flat 
land.  The  two  mountain  ranges  skirt  this  central  valley,  proceeding  in 
long,  sweeping  curves  to  a  convergence  at  Tehachapi  Pass,  three- 
(piarters  the  way  down  the  state  from  its  north  boundary.  From  this 
point  on  to  the  Mexican  border,  the  mountains  are  grouped  in  a  com- 
plex aggregation  which  apportions  the  south  part  of  this  state  between 
tile  Pacific  slope  and  the  desert  expanse  that  is  the  southeast  corner  of 
California.

18  WATER  RESOURCES   OF   CALIFORNIA. 

Undifferentiated  at  tlie  state's  northern  and  southern  extremities, 
tlie  two  ranges  are  definitely  separated  in  the  middle  of  tlieir  course, 
ftliere  they  enclose  the  nearly  sea-level  vallcx'  within  a  rock  wall  which 
i.s  cleft  in  but  one  place  to  valley -floor  level.  Througli  this  cutting  the 
interior  drainage  issues,  flowing  westwardly.  and  mingles  with  the 
water.s  of  the  Pacific  Ocean.  Exit  from  this  mountain-engirdled  valley 
by  other  than  this  sea-level  cut  is  over  passe-i  that  traverse  the  moun- 
tain chains.  These  passes,  limited  in  number,  are  approached  by  tor- 
tuous ascents  to  attain  their  elevation,  for  the  lowest  of  these  notches 
tliat  give  egress  to  the  east  is  5200  feet  in  elevation. 

The  easterly  mountains,  tlie  Sierra  Nevada  Range,  originating 
toward  Mount  Shasta  and  terminating  at  Teliachapi  Pass,  have  a 
long  and  somewhat  uniform  slope  from  their  crest  toward  the  west. 
This  westerly  slope  is  broken  by  a  series  of  ridges  forming  crests 
secondary  to  the  main  crest  of  the  range.  The.se  subsidiary  ridges, 
paralleling  the  course  of  the  dominating  heights  of  the  mountain 
ciiain,  have  crumpled  crests,  are  broken  down  in  places  and  cross-cut 
by  surface  drainage,  and  are  monumented  by  erosion-resisting  peaks. 
Tile  westerly  slope  occupies  from  a  (piarter  to  a  third  of  the  breadth 
of  the  state  in  descending  to  the  plains  level  of  the  great  central  valley, 
from  the  line  of  crests  on  the  axis  of  the  range.  To  the  east  the 
Sierra  Nevada.s  present  a  steep  escarpment  composed  of  abruptly  rising 
rock  walls,  precipitous  cliffs  and  talus  slopes  with  few  discernible  fold- 
ings, secondary  to  the  main  ridge.  The  crests  of  this  range  increase  in 
altitude  from  north  to  south.  Lassen  Peak,  in  the  northern  quarter 
of  this  ranae,  the  one  active  volcano  in  the  United  States,  overlooks  the 
adjacent  mountains,  and  is  10,580  feet  high.  To  the  south,  the  crest  of 
the  range,  increasing  in  height  culminates  the  upreared  crust  of  the 
earth  in  :Mount  Whitney  in  the  .southern  quarter  of  the  range,  at  14.500 
feet  high,  the  highest  mountain  in  the  United  States,  excluding  Alaska. 

The  Sierra  Nevada  Range  is  very  diverse  in  .surface  features.  The 
crests  are  serrated,  rocky,  soilless  and  precipitous.  The  slopes  are  gen- 
erally tree-covered  wherever  soil  has  found  lodgment.  The  troughs 
between  the  successive  folds  of  the  earthen  crust  form  mountain 
meadows,  marshy  flats  and  upland  lakes,  and  intricately  interlaced 
throughout  the  entire  extent  of  this  range  are  brooks,  .streams  antl 
rivers. 

The  main  drainage  channels  cross  the  secondary  ridges  in  the 
water's  descent  from  the  crest  of  the  range,  while  the  tributary 
streams  largely  traverse  the  grooves  between  the  successive  folds  that 
parallel  the  axis  of  the  range.  The  main  stream  channels,  in  crossing 
the  sul)>;idiary  corrugations  of  the  mountain  chain  and  cutting  through 
the  intervening  ridges,  are  deeply  eroded  into  the  mountain  structure, 
and  llow  through  water-worn  canyons  and  gorges  that  expose  the  seams 
and  layers  of  the  mountain  stratifieation  as  etchings  on  their  pi-ecipitous 
cliffs.  The  beds  of  the  cross  channels  are  cut  and  lowered  luitil  they 
arc  often  far  below  the  beds  of  the  tributary  channels  which  empty 
the  lateral  drainage  from  the  troughs  between  the  lines  of  the  secoiul- 
ary  cre.sts  that  corduroy  the  mountain  slopes.  The  abrupt  descent  of 
the  tributary  waters  that  flow  into  the  cross-cut  gorges,  forms  cascades 
and  waterfalls,  and  of  these,  the  Yosemite  Falls  in  the  heart  of  the 
Sierra  Nevadas,  is  the  highest  in  the  world,  leajiing  2500  feet  from 
the   mouth   of  a  tributarv   vallev   info   the   ]\[erced    River   gorge.     So 


WATER   RE^OFRCES    OF    CALIFORNIA.  19 

jjotent  has  been  the  eroding  force  in  cntting  these  canyon.s  and  gorges 
across  the  folds  of  the  mountain  structure,  that  many  of  these  deeply 
incised  channels  have  cut  back  to  the  very  base  of  culminating  peaks 
of  the  range,  where  their  low-lying  beds  at  the  bottom  of  the  chasms 
are  but  half  as  high  as  the  dominating  peaks  that  tower  above  them. 

The  streams  in  the  Sierra  Xevadas,  except  where  tlowing  in  the 
valleys  and  meadows  between  the  mountain  folds,  are  turbulent  waters, 
ilowing  over  boulder-strewn  beds,  through  shadowy  gorges,  swirling 
down  steep  descents  in  foaming  cascades  until,  approaching  the  valley 
tl(>or,  they  sweep  out  upon  the  plains  to  pursue  their  oceaiiward  .jour- 
ney over  gravelly  beds  of  more  moderate  gradients.  The  drainage  of 
the  westerly  slope  of  this  range  collects  into  the  Sacramento  and  San 
Joaquin  rivers,  the  two  largest  rivers  in  the  state.  These  rivers,  two 
meandering  channels  with  tree-covered  banks,  sandy  beds,  and  swampy 
flats  of  tule  growth,  follow  the  axis  of  the  great  central  valley  that 
is  fenced  by  the  mountain  ranges.  One  river  originating  in  the  north 
and  flowing  southerly,  and  the  other  rising  in  the  south  and  flowing 
northerly,  unite  to  the  eastward  of  the  sea  inlet,  through  which  their 
combined  waters  enter  the  Pacific  Ocean  through  the  Golden  Gate. 

■The  easterly  slope  of  the  Sierra  Nevadas  presents  a  rocky  rampart 
of  abrupt  acclivities  and  precipitous  walls  which  has,  because  of  its 
greater  steepness,  a  smaller  water  collecting  area  than  the  opposite  slope 
on  the  west.  So  much  smaller  is  this  area  in  the  greater  water-produc- 
ing regions  of  the  high  altitudes,  that  no  rivers  are  formed  on  the  eastern 
slopes  of  the  Sierra  Nevadas  that  compare  in  magnitude  to  those  on 
tiie  west.  This  easterly  slope  of  the  Sierra  Nevadas  is  but  a  twentieth 
to  a  tenth  of  the  width  of  the  state,  in  descending  from  the  predomi- 
nating crests  along  the  axis  of  the  range  to  the  agricultural  valleys 
that  skirt  the  mountain  edges  and  fringes  of  the  talus  slopes  along 
the  easterly  border  of  the  state.  These  agricultural  valleys  are  located 
at  from,  four  to  seven  thousand  feet  in  elevation  and  are  on  the  west- 
erly margin  of  the  Great  Basin  which  extends  easterly  from  the  Sierra 
Zsevadas  to  the  Rocky  ^Mountains.  The  waters  of  the  .streams  drain- 
ing the  eastern  slope  of  the  Sierra  Nevadas  collect  for  a  quarter  of 
the  length  of  the  mountain  chain  by  flowing  into  Ov/ens  River  in 
Owens  Valley,  which  parallels  the  range  along  its  eastern  toe.  Beyond 
this  confluence  of  waters,  there  is  no  great  collection  of  drainage  into 
large  rivers,  and  none  of  these  waters  reach  the  ocean,  but  instead, 
lose  themselves  in  sinks  or  by  entering  land-locked  lakes  where  they 
are  dissipated  through  evaporation. 

The  westerly  of  the  two  mountain  chains,  called  the  Coast  Range 
Mountains,  after  separating  at  Mount  Shasta  from  the  mass  of  moun- 
tains in  the  northern  part  of  the  state,  parallels  the  Pacific  Ocean's 
margin  and  takes  a  narrower  and  straighter  path  in  its  southerly 
course  than  does  the  Sierra  Nevada  range.  These  Coast  ^Mountains 
do  not  attain  the  elevations  reached  by  the  Sierra  Nevada  >\[ountains, 
neither  are  they  so  diverse  or  massive  in  structure.  The  highest  peaks 
between  the  Oregon  Hne  and"  the  Tehachapi  are  less  than  9000  feet  in 
elevation,  and  the  peaks  above  5000  feet  are  but  few  in  number.  A 
third  of  the  way  down  the  state  from  the  Oregon  line,  Mount  Diablo 
and  Mount  Hamilton  surmount  the  range  at  8850  and  4210  feet, 
respectively.  Two-thirds  the  way  down  the  state,  Pinos  .Mountain 
reaches  to  8826  feet  in  height,  and  from  this  the  range  continues  east- 


20  WATER  RESOURCES  OF   CALIFORNIA. 

erly  with  occasional  crests  ahiiost  as  high  until  reacliint;-  Tehaehapi 
Pass,  4000  feet  above  sea  level.  The  traveled  passes  in  the  Coast  Range 
Mountains  are  considerably  lower  tlian  those  of  the  Sierra  Nevadas. 
They  are  located  at  elevations  of  from  750  to  4200  feet  and  are  ])a.ssable 
throughout  the  year,  while  through  the  Sierras  the  lowest  pass  is  5200 
feet,  and  railroad  communication  only,  is  maintained  through  tunnels 
and  snowsheds. 

The  Coast  Range  Mountains  are  largely  composed  of  sedimentary 
rocks.  The  igneous  rocks,  where  they  exist,  are  seamed,  friable  and 
easily  broken  down.  The  crests  of  this  range  present  a  more  rounded 
profile  and  the  hills  are  more  rolling  and  less  rugged  than  the  Sierra 
Nevadas.  In  the  northern  parts  these  mountains  are  forest-clad,  but 
are  only  scatteringly  timbered  in  the  south.  The  base  of  this  range 
IS  a  quarter  to  a  third  of  the  width  of  the  state,  being  broader  toward 
the  northerly  end. 

This  range  is  penetrated  by  a  salt  water  inlet  at  about  its  middle 
point  between  Mount  Shasta  and  Tehaehapi  Pass  and  one-third  the 
distance  down  the  state  from  its  north  boundary.  This  inlet  is  cut  to 
depths  below  sea  level  and  admits  salt  or  brackish  water  almost  into 
the  state's  central  valley.  Land-locked  and  encircled  by  hills  and 
mountains,  the  bays  of  San  Francisco  and  San  Pablo  make  this  inlet 
one  of  the  great  harbors  of  the  world.  Through  this  cutting  in  the 
Coast  Range  ^Mountains,  the  drainage  of  the  great  central  valley,  the 
.east  slope  of  the  Coast  Range  Mountains,  the  w-est  slope  of  the  Sierra 
Nevada  ]\Iountains,  and  the  plateau  regions  in  the  northeastern  corner 
of  the  state  finds  its  way  to  the  Pacific  Ocean.  These  waters,  the 
drainage  of  one-third  the  area  of  California,  comprise  a  half  of  all  the 
waters  of  the  state. 

The  folds  of  the  earth's  crust  which  form  the  Coast  Mountains  are 
approximately  parallel  to  each  other  and  to  the  axis  of  the  range. 
These  corrugations  in  the  earth's  crust  are  clearly  defined,  and  com- 
pared to  the  Sierra  Nevadas,  the  valleys  between  the  folds  are  of  a  more 
regular  surface  conformation  and  of  an  extended  length.  The  agri- 
cultural lands  of  the  Pacific  region  are  located  in  these  valleys  and"on 
the  detrital  flats  near  the  ocean  margin. 

Exclusive  of  Khiiiath  River,  the  main  drainage  channels  of  the  Coast 
Range  follow^  tjretroughs  between  the  mountain  folds  and  receive  the 
waters  of  s|iP^ms  which  drain  the  slopes  of  the  ridges  to  either  side. 
These  waters  flowing  in  the  major  channels  of  the  valleys  all  drain 
northward  and  northwesterly,  excepting  Russian  River,  \vhich  flows 
southward  throughout  most  of  its  course  until  it  turns  west  and  cuts 
the  axis  of  secondary  ridges  of  the  (^oast  Mountains  to  empty  its  waters 
into  the  Pacific  Ocean.  The  Coast  Range  has  fewer  crosscut  water 
channels  transverse  to  the  secondary  ridges  than  the  Sierra  Nevadas, 
but  the  principal  axis  of  the  chain  is  deeply  cut  in  two  places:  at  the 
salt  water  inlet  through  the  Golden  (Jate.  and  at  Klamath  River  which 
enters  the  state  from  the  north,  cuts  through  the  main  axis  of  the  Coast 
Mountains  west  of  Mount  Shasta,  and  carries  the  drainaire  of  the 
eastei-n  slope  of  the  Coast  Mountains  in  California  and  Oreuwi,  across 
the  main  mountain  i-ange  and  into  the  Pacific  Ocean. 

Between  the  Pacific  littoral  and  the  western  foldings  of  the  Coast 
Mountains  are  coastal  plains,  deltas,  and  detrital  fiats,  formed  from  the 


WATER    RE'^OURCES    OF    CALIFORNIA.  21 

attrition  of  the  mountain  structure.  Tliese  coastal  tiats  are  located  at 
the  ocean  outlet  of  the  streams  and  are  scattered  rather  meagerly 
along  the  Pacific  margin  from  the  Oregon  line  to  the  Santa  Barbara 
Channel.  Their  continuity  is  interrupted  by  extensive  stretches  of 
precipitous  shore  line  that  rises  abruptly  from  the  water's  edge.  South- 
erly from  the  Santa  Barbara  Channel,  these  coastal  plains  are  more 
extensive  and  proceed  almost  continuously  from  near  Los  Angeles  to 
the  Mexican  border,  a  strip  one-sixth  the  length  of  the  state. 

The  streams  draining  the  west  slope  of  the  Coast  ^Tountains  are 
mostly  perennial,  but  the  eastern  slope  of  this  range  is  drained  by 
water  courses  which  seldom  flow  continuously  throughout  the  year. 
In  that  portion  of  the  Coast  Range  that  lies  between  the  Golden  Gats 
and  Tehachapi  Pass,  the  water  in  the  eastwardly  flowing  streams  is 
so  meagre  during  the  summer  season  that  few  have  surface  water, 
and  none  of  them  ever  maintain  a  continuous  thread  of  water  in  their 
channels  to  a  confluence  with  the  great  river  of  the  central  valley. 

All  the  streams  of  this  westerly  range  have  a  more  moderate  grad- 
ient than  do  the  water  channels  of  the  Sierra  Nevada  Mountains. 
Arising  in  mountains  of  lesser  elevation  and  flowing  over  a  rocky  for- 
mation that  is  more  easily  eroded,  the  streams  pass  through  their 
delrital-filled  valleys  and  wend  their  way  toward  the  sea  following  a 
more  dilatory  course  than  the  deeply  cut  major  channels  of  the  Sierras. 

The  slopes  of  the  Coast  Mountains  toward  the  Pacific  Ocean  that 
lie  north  of  the  Golden  Gate  are  generally  heavily  forested,  but  back 
from  the  coast  the  timbering  is  less  dense.  This  range  north  of  Clear 
Lake  and  particularly  the  region  west  of  Mount  Shasta,  is  clothed  in 
almost  continuous  forest.  Northerly  from  the  Golden  Gate  the  agri- 
cultural areas  are  relatively  small  in  size.  The  largest  of  the  coastal 
valleys,  the  Eel  River  Valley,  at  the  mouth  of  the  Eel  River,  contains 
90  square  miles  of  agricultural  land.  In  the  interior  the  agricultural 
areas  are  in  the  valleys  adjacent  to  Clear  Lake,  and  between  that  lake 
and  San  Francisco  Bay.  The  most  extensive  area  of  agricultural  land 
is  in  the  group  of  valleys  contiguous  to  Santa  Rosa  and  comprises  1-iO 
square  miles  of  tillable  land.  Between  San  Francisco  Bay  and 
Tehachapi  Pass  the  timbering  is  often  sparse  and  the  forests  there  are 
entirely  confined  to  the  Pacific  slope  of  the  range. 

The  assemblage  of  mountains  in  the  northern  part  of  the  state,  which 
include  the  conjunction-  of  the  Coast  Range  and  Sierra  Nevada  Moun- 
tains, extends  from  the  sea  coast  to  the  Nevada  line  and  from  Honey 
Lake  to  the  Oregon  boundary.  They  are  interspersed  with  peaks  and 
cones,  having  sharply  cut  notches  and  scalloped  slopes,  and  so  dense 
are  they  aggregated  in  the  region  between  Mount  Shasta  and  the 
Pacific  Ocean  that  tiiere  are  almost  no  flat  areas.  East  of  Mount 
Shasta,  and  extending  a  fifth  of  the  way  down  the  state  from  the  north 
border,  is  a  lava  cap  that  forms  a  mountain  plateau  on  the  easterly 
side  of  the  Sierras,  4000  to  6000  feet  in  elevation.  Divided  by  Pit 
River  and  extending  northerly  to  Oregon  and  southerly  to  Lake 
Almanor  and  Honey  Lake,  this  region  presents  a  syrface  of  hummocks 
and  hills  of  lava,  irregularly  interspersed  over  an  extensive  plains- 
area  of  lava  soil.  This  lava  is  shattered  into  angular-shaped,  jagged 
chunks,  and  covers  the  surface  of  the  region  to  underterniined  depths. 
These  beds  of  eruptive  rock  have  been  cleft  into  fissures  that  extend 
many  miles  in  length.  Spread  over  this  region  are  cinder  cones,  extinct 
craters,  steam  vents  and  hot  springs.

On  this  area  the  precipitation  easily  penetrates  the  absorptive  cover- 
ing of  lava  and  tlie  interstices  and  apertures  between  the  rock  frag- 
ments, or  into  the  cellular  honeycomb  structure  of  the  steam  blown 
volcanic  rock.  This  i)ortion  of  the  state  contrasts  itself  with  the 
remainder  of  California  in  having  an  abundance  of  subterranean 
waters  that  appear  as  springs.  These  furnish  a  substantial  and  per- 
eiiuial  supph'  of  water  to  the  streams  draining  the  region ;  some  of  the 
springs  pouring  out  their  waters  uniformly  and  in  volumas  of  one 
hundred  cubic  feet  per  second  or  more,  give  immediate  and  consider- 
able flow  to  the  water  channels  having  them  as  their  source.  The 
largest  of  these  streams.  Pit  River,  which  drains  half  of  this  lava  cap, 
rises  in  the  extreme  northeastern  part  of  the  state,  crosses  the  axis  of  the 
Sierra  Nevada  ^Mountains  to  a  confluence  with  the  Saeramento  River, 
and  is  the  only  stream  that  carries  any  drainage  from  the  easterly  slope 
of  this  range  into  the  long,  central  valley  which  lies  between  the  Ooa.st 
Range  and  the  Sierras. 

Klamath  River,  whieli  drains  the  mountainous  region  north  and  west 
of  Mount  Shasta,  is  one  of  the  few  rivers  of  the  United  States  that 
carries  any  drainage  of  the  Great  Basin  through  the  axis  of  a  mountain 
range.  It  has  its  source  in  Oregon  where  it  drains  a  portion  of  the 
eastern  slope  of  the  Cascades,  flows  southerly  into  California  to  the 
Horthwat'd  of  the  Pit  drainage  and  thence  westerly,  crossing  the  axis 
of  the  Coast  ^fountains  through  the  Klamath  Gorge,  and  empties  its 
waters  into  the  Pacific  Ocean  within  35  miles  of  Oregon. 

Strung  cliain-like  from  the  lower  end  of  Goose  Lake  along  Pit  River 
is  a  group  of  agricultural  valleys.  The  tillable  lands  are  on  the  floors 
of  the  valleys  and  on  the  slopes  rising  from  them.  Jjetween  this  cordon 
of  valleys  and  Honey  I^ake  are  located  Madeline  Plains,  Round  and 
Ploney  Lake  valleys.  The  largest  of  these.  Honey  Lake  Valley,  con- 
tains 820  square  miles  of  tillable  land.  East  of  the  Pit  River  chain  of 
^'alleys  is  Surprise  Valley,  which  contains  Copper,  Lower  and  ^Middle 
Lakes  on  the  margins  of  which  agricultural  lands  are  located. 

Covering  the  major  portion  of  Southern  California  is  the  southward 
continuation  of  the  state's  two  main  mountain  ranges,  which  after 
tiieir  convergence  at  Tehachapi  Pass  proceed  in  a  diversified  aggrega- 
tion of  mountains  that  extend  to  the  Mexican  border.  These  partake 
of  the  characteristics  of  both  the  Coast  Range  and  Sierra  Nevada 
Mountains,  as  some  are  angular  i)rofusions  of  rock;  others  are  rounded, 
soil-covered  and  rolling.  Usually  steep  of  slope,  almost  precipitous, 
these  mountains  are  deeply  furrowed  by  sharp-cut  gullies  and  ravines, 
and  have  canyons  filled  with  underbrush,  and  water  courses  lined  with 
alders,  sycamore  and  willows.  A  dense  brush  cover  clothes  their 
rugged  slopes,  but  timber  grows  only  at  the  higher  elevations. 

The  crest  of  this  range  is  lower  than  that  of  the  Sierra  Nevada 
Monntains,  with  less  continuity  of  arrangement.  A  few  dominating 
peaks  rise  to  heights  of  more  than  10,000  feet,  but  their  general  alti- 
tude is  comi)arable  to  that  of  the  Coast  Range.  The  passes  over  them 
are  intermediate  in  elevation  between  those  of  the  Coast  Range  and 
Sierra  Nevada  Moujitains,  are  snowiest;  except  at  intervals,  aiid 
traversible  throughout  the  entire  year.  This  mountain  range  divides, 
and  the  routes  through  the  passes  connect,  two  diverse  regions.  To  the 
west,  the  Pacific  slope,  the  agricultural  lands  of  which  extend  from 
tlie  ocean   margin   well   up   to   the   mountain  flanks,   is  a  developed, 


WATER    HI'>01TRCI<:S    OF    CALIFORNIA.  23 

i't'i'tile,  productive  area  of  moderate  climatic  fluctuation:  to  the  east 
is  tlie  desert,  an  undevelo])ed  region  of  great  extent,  almost  rainless 
and  uon-pi'oductive  thi'ough  lack  of  an  accessory  water  supply,  'riu^ 
only  extensive  productive  areas  are  the  Imperial,  Palo  Verd(>  and 
Coaehella  valleys  which  have  acquired  irrigation  supplies  and  are  realiz- 
ing on  the  great  fertility  of  the  desert  soil.  In  this  expanse  of  rainl(\ss 
desert  is  Salton  Sink,  an  inland  sea,  the  surface  of  which  is  more  than 
250  feet  below  the  ocean  level.  Its  surface  is  gradually  lowering 
through  evaporation. 

The  stream  channels  draining  into  the  desert  from  the  mountains 
that  separate  it  from  the  Pat'ific  region,  are  dry  throughout  most  of 
tlie  year.  Excepting  those  streams  that  have  their  source  at  high  eleva- 
tions, flow  in  the  water  channels  occurs  only  after  an  appreciable 
pr(H'ipitation  has  fallen  upon  th.e  slopes  of  the  tributary  drainage  basins. 
No  large  streams  are  formed  by  the  waters  drained  from  this  eastern 
slope  and  none  of  its  drainage  reaches  the  ocean ;  instead,  it  is  lost  by 
seeping  into  the  arid,  desert  soil  and  through  evaporation.  The  streams 
draining  the  western  slope  of  these  mountains  are  perennial  and,  after 
descending  the  steeper  mountain  slopes,  pass  through  broad,  detrital- 
filled  valleys,  pursuing  generally  a  direct  course  to  the  ocean.  Large 
areas  of  fertile  agricultural  land  border  the  streavns  in  these  valleys 
and  extend  to  the  ocean's  shore  which  the  streams  approach  between 
banks  but  slightly  above  their  beds. 

With  three-fifths  of  the  surface  of  California  disposed  in  mountains, 
the  extreme  range  of  altitude  is  from  275  feet  below  sea  level  in  Death 
Valley,  to  14,500  feet  above,  attaining  this  elevation  at  Mount  Whitney 
but  seventy-five  miles  distant  from  the  lowest  depression.  The  greater 
part  of  the  flat  lands  of  the  state,  or  about  one-fifth  of  its  total  area, 
lies  between  the  elevation  of  the  ocean 's  edge  and  500  feet  above.  They 
comprise  the  gently  sloping  ocean  littoral,  an  extensive  mountain- 
girdled  valley  known  as  the  Sacramento-San  Joaquin,  and  desert  areas 
in  the  southeastern  part  of  the  state.  This  region,  33,000  square  miles 
in  extent,  includes  the  bulk  of  California's  agricultural  area."  Higher 
in  elevation  than  these  flat  lands,  are  gentle  slopes  lying  between  the 
plain-like  areas  and  the  base  of  the  mountains.  These  are  the  rolling 
foothills  and  detrital-filled  valleys,  lands  that  are  transitional  to  plain 
and  highland  regions.  These  are  located  mostly  between  500  and  2500 
feet  above  sea-evel,  and  53,000  square  mile.s,  or  about  one-third  the  area 
of  the  state,  lie  between  these  elevations.  One-quarter  of  the  agri- 
cultural land  of  the  state  is  in  this  region  and  only  the  scattered  parcels 
in  high  mountain  valleys  and  that  on  the  plateau  of  northeastern 
California  lie  above  it. 

The  area  aliove  the  2500-foot  elevation,  72,000  scpuii'e  miles  in  extent 
or  about  half  the  state's  area,  the  mountains  proper,  comprise  the  rock- 
strewn  slopes,  steep  acclivities,  sheer  cliffs,  rocky  extrusions,  serrated 
riducs,  and  mountain  crests — su.rmounted  by  storm-swept  pinnacles. 
Of  this  region,  35,000  square  miles  or  one-fifHi  the  surface  of  Cali- 
fornia, lies  above  5000  feet.  The  mountain  and  foothill  regions 
together,  are  over  triple  the  area  of  th(>  agricultni-al  lands  and  receive 
a  greater  ])reeii)itatii)n.  This  mountain  water-producing  area  sheds 
its  run-ofif:'  into  streams  and  rivers  which  traverse  the  valley  and  ])lains 
areas  in  their  course  to  tlie  wa1er  clianncl's  nioulh  at  the  ocean  margin.

CHAPTER  II. 


PRECIPITATION. 

]\[an,  in  common  with  all  other  life  on  this  earth,  is  horn,  passes  his 
entire  existence  and  dies  without  ever  emerging  from  water  in  which 
he  is  surrounded.  (Jovering  the  eartli  from  pole  to  pole  and  extending 
from  the  ocean's  greatest  dejiths  to  far  over  the  tops  of  the  liig'hest 
mountains,  even  penetrating  to  a  considerable  distance  the  soils  and 
rocks  upon  which  it  rests,  this  fluid  fills  the  lower  depressions  of  the 
earth's  surface  in  the  liquid  form;  but  above  the  sea  and  the  land,  it 
wraps  the  entire  globe  in  an  all-pervading  sheath  of  water-vapor  that 
mingles  with  the  atmosphere.  Although  invisible,  this  sea  of  water- 
vapor  extends  many  miles  upward  from  the  surface  of  the  earth ;  in 
sensible  concentrations,  however,  it  is  confined  within  the  lower  five 
miles.  The  liquid  water,  one  eighth-hundredth  the  bulk  of  the  earth,  is 
of  sufficient  volume  to  blanket  the  globe  with  a  continuous  sheet  of 
water  that  submerges  three-quarters  of  the  solid  crust.  In  the  cold  of 
the  polar  regions  this  water-blanket  is  rigid  and  solid,  and  mantles 
the  earth  with  ice  floes  which  attain  the  dimensions  of  continents. 

Ceaselessly  changing,  one  into  another,  the  liquid  and  solid  waters 
of  the  earth  evaporate  and  enter  the  invisible  vapor-envelope,  and  at 
all  times,  somewhere,  atmospheric  waters  are  precipitating  from  this 
vapor-envelope  to  rejoin  the  bulk  of  the  waters  of  this  planet  in  the 
liquid  or  solid  state.  This  interchange  between  the  visible  and  the 
invisible  waters  is  in  progress  continually,  differing  in  degree  of 
activity,  but  ever  striving  to  effect  an  equilibrium  between  the  natural 
tendencies  of  the  liquid  and  solid  water  to  diffuse  as  vapor,  and  the 
vaporized  waters  to  liquify  or  congeal. 

The  physical  phenomenon  inciting  the  interchange  between  the  visilile 
and  invisible  waters  of  the  globe,  is  the  temperature  of  the  atmosphei-e 
and  of  the  lithosphere  which  the  vaporous  waters  contact.  Fluctnatiug 
with  the  rotation  of  the  earth,  these  temperatures  ])ass  through  a 
daily  cycle  of  alternate  warmth  and  coolness.  With  the  rising  and 
setting  of  the  sun,  all  parts  of  the  earth  are  subject  to  cyclic  changes 
of  temperature,  and  these  fluctuations  progress  around  the  globe  as 
the  sun's  raj^s  sweep  over  its  surface.  The  atmosphere  and  lithosphere 
are  warmed  by  the  heat  of  sunshine  during  the  day,  and  cooled  by 
the  radiation  of  heat  during  the  darkness  of  night  hours.  Varying 
quantities  of  heat  are  absoi-bed  l)y  the  air,  the  water,  and  the  soil  and 
rocks  of  the  earth's  crust,  as  tiie  sun's  rays  pierce  the  enshrouding  gas 
envelope  and  penetrate  to  tlie  bottom  of  the  atmos})lieric  ocean.  Tiie 
rocks  and  soils,  endowed  with  a  gi-eater  cajiacity  for  absoi'bing  heat, 
rise  in  temperatui'e  more  slowly  than  the  gases  of  the  air,  but  the 
li(juid  waters  of  the  lakes  and  oceans,  having  a  still  larger  absorptive 
power  than  either,  are  the  most  sluggish  in  their  thermal  change.  In 
the  absence  of  the  warming  rays  of  the  sun,  the  atmosphere  is  lowered 
in  temperature  the  more  rapidly,  having  less  heat  to  radiate,  the  soil 
and  rocks  next,  and  tlie  waters  of  the  earth  the  least  rapidly  of  all. 


WATER    RESOURCES    OF    CALIFORNIA.  25 

It  thus  occurs  that  the  air,  the  earth,  and  the  sea  are  constantly 
in  the  process  of  thermal  change,  ever  endeavoring  to  reach  like  tem- 
perature to  the  heat  of  day  or  the  cold  of  night.  With  each  temperature 
rise,  the  ability  of  the  atmosphere  to  occlude  water-vapor  becomes 
greater  and  the  tendency  for  solid  or  liijuid  water  to  vapori/.e  increases, 
so  that  as  temperatures  rise,  the  liciuid  and  solid  waters  tend  to  diffuse 
into  the  air  as  aqueous  vapor;  but  as  the  temperatures  fall,  vaporized 
waters  of  the  air  tend  to  liquidize  or  congeal.  The  daily  thermal  cycle, 
therefore,  in  sweeping  around  the  surface  of  the  earth  at  the  rate 
of  1500  feet  per  second,  leaves  behind  it  a  riotous  endeavor  on  the  part 
of  the  earthly  elements  to  adjust  themselves  to  their  ever  changing 
heat  environuunit  and  to  reeoncik'  the  disturbed  balance  l)etween  the 
visible  and  invisible  waters  of  the  gh)be.  These  interchanges,  continu- 
ing unceasingly,  are  called  dews,  fogs,  mists,  rain,  downpours,  or  cloud- 
bursts as  the  precipitation  of  condensed  moisture  from  the  invisible 
vaporous  envelope  becomes  more  intense ;  but  as  the  visible  liquid  or 
solid  waters  diffuse  to  join  the  vaporous  envelope  the  interchanges  are 
called  evaporation,  and  this  is  said  to  be  slow  or  rapid  in  accord  with 
the  readines  of  diffusion. 

Coincident  wntli  these  thermal  agitations,  areas  of  low  pressure 
appear  in  the  atmosphere  as  this  swirls  wath  the  rotation  of  the  earth. 
Meteorological  observations  of  the  United  States  "Weather  Bureau  show 
tliat  areas  make  their  appearance  along  the  Alaskan  Coast,  in  which 
the  pressure  of  the  atmospheric  envelope  surrounding  the  earth  is  less 
than  in  adjacent  regions.  Successive  observations,  taken  subsequently, 
reveal  these  low  pressure  areas  in  movement  southeasterly  across  the 
continent,  to  be  finally  dissipated  by  equalization  of  pressure  through 
air  movements,  or  to  endure  and  pass  out  into  the  ocean  from  the 
Atlantic  shore  of  this  continent.  With  the  formation  and  progress 
of  these  areas  of  low  pressure,  winds  arise  that  are  directed  toward 
them,  and  the  air  flows  from  hundreds  of  miles  distant  to  equalize  the 
variant  pressures. 

In  California  the  prevailing  winds  are  from  the  south,  southwest, 
and  west,  rushing  toward  the  areas  of  low  pressure  as  these  pursue  their 
diagonal  course  across  the  continent.  Sometimes,  however,  centers  of 
low  pressure  enter  the  state  from  off'  the  Pacific  Ocean  at  which  times 
easterly  or  northerly  winds  may  blow  over  parts  of  the  state.  These 
air  movements  may  be  concentrated  in  volume  or  altered  in  direction 
locally,  by  hills  or  mountains  or  the  passes  between  them,  so  that  the 
winds  of  the  lower  atmosphere  may  often  be  at  variance  with  the  direc- 
tion of  the  more  widespread  air  movements. 

The  winds  may  blow  as  gentle  l^reezes  or  attain  to  the  velocity  of 
gales,  in  accord  witli  their  nearness  to  the  low  pressure  areas  or  the 
degree  to  whicli  their  pressures  arc  ])elow  those  of  the  surrounding 
regions,  and  they  are  called  zephyrs,  ])reezes,  winds,  gales,  or  cyclones 
as  they  have  greater  speed  of  movement.  Velocities  of  air  movement 
have  l)een  recorded  as  great  as  130  miles  per  hour  before  the  instru- 
ments of  observation  were  demolislied,  but  velocities  exceeding  thirty 
miles  per  hour  are  unusual. 

This  movement  of  air  from  one  locality  to  another  to  equalize  differ- 
ences of  barometric  pressure  in  the  eartli's  atmosphere,  is  the  primary 
feature  of  storms.  Transporting  air  from  one  area  to  another  exposes 
it  to  new  temperature  conditions^  and  as  adjustment  takes  place  by 


26  WATER   RESOURCES    OF    CALIFORNIA. 

the  flow  of  lu'at  from  the  manner  element  to  the  cooLt,  if  tlu^  temi)era- 
ture  of  the  air  is  reduced,  its  Yai)or  couteiit  for  the  lowered  tempera- 
ture may  exceed  its  new  holding-capacity,  and  the  excess  moisture  may 
then  be  expelled  from  the  atmosi)here  and  fall  to  the  earth's  surface  as 
rain  or  snow.  It  is  the  lowering  of  the  temperature  of  the  atmosphei'(> 
so  much,  that  at  its  new  temperature  it  is  unable  to  hold  all  the  water- 
vapor  present,  that  creates  the  change  of  the  invisible  waters  of  tlie 
earth  to  the  visible.  When  this  change  attracts  the  attention  of  man. 
because  of  the  inconvenience  caused  him  in  his  daily  pursuits  by  the 
wetting  of  his  environment,  it  is  commonly  named  a  "storm,"  but 
minor  precipitations  are  continually  in  occurrence  from  similar  causes 
and,  not  being  culminations  of  aei-ial  disturbances  nor  violent  in  their 
intensity,  they  pass  unnoticed.  The  daily  fluctuation  ol:  temperatui'c 
in  (me  locality  is  often  sufficient  to  lessen  the  water-vapor  holding- 
capacity  of  the  atmosphere  at  the  coldest  phase  of  the  cycle;  then  the 
cold  of  the  night  may  cause  slight  preciY)itation,  and  dew,  fug,  or 
frost  may  form,  but  for  precipitation  to  occur  in  volume,  a  movement 
is  necessary  of  vapor-saturated  air  to  localities  of  a  cooler  temperature. 

California,  spread  out  along  the  shore  of  the  Pacific  Ocean  for  a 
length  of  900  miles,  experiences  favorable  meteorological  conditions 
for  precipitation  in  sufficient  volume  to  be  called  a  "storm,"  only 
during  the  season  when  vapor-saturated  air  from  off  the  ocean  is  cai-ried 
overland  to  contact  with  the  cooler  lithosphere.  This  season  is  wintei-, 
being  one  part  of  the  annual  cycle  of  exchange  of  heat  between  the  sun, 
earth,  sky,  rocks,  and  sea,  which  gives  variance  to  the  daily  cycle  of 
exchange  from  day  to  night.  This  annual  cycle  is  caused  bj^  the  chang- 
ing inclination  of  the  earth's  axis  of  daily  rotation  in  circling  its  yearly 
orbit. 

Throughout  the  summer  season,  quantities  of  heat  reach  the  surface 
of  the  earth,  and  this  warms  the  rocks,  the  soil,  and  the  water.  The 
rocks  and  soil,  requiring  as  they  do  a  less  amount  of  heat  than  does 
water  to  increase  their  temperature  to  an  equivalent  degree,  soon  become 
the  warmer.  Witli  the  coming  of  the  winter  season,  less  quantities  of 
heat  penetrate  the  atmosphere  to  the  earth's  crust  and  a  radiation  of 
heat  occurs  from  both  land  and  water.  As  the  rocks  and  soil  readil\- 
give  up  their  heat  and,  having  less  stored  heat  than  the  waters  of  Ihe 
ocean,  the  land  area  sooon  reaches  a  condition  of  temperature  that  is 
lower  than  that  of  the  water.  It  is  only  at  this  time  of  the  year  that 
the  translation  of  the  ocean  air  to  contact  with  the  cooler  land,  lowci's 
its  temperature  enough  to  produce  over-saturation.  Thus  conditions 
favorable  to  precipitation  occur  as  this  air,  heavy  in  water-va])or,  is 
moved  over  the  cooler  land  by  the  Avinter  winds.  Of  the  seasons  inter- 
mediate between  summer  and  winter,  it  nmy  be  observed  tliat  rains 
generally  fall  over  the  land  during  the  cold  of  night,  since  at  this  time 
only,  is  there  sufficient  contrast  in  tcmix'ratui-e  with  the  inHowinu 
ocean  air,  to  cool  the  winds  enough  for  pi-ecipitation  to  occur.  Even  in 
the  dead  of  winter  the  heaviest  showers  occur  more  fre(iuently  at  night. 

The  warmer  temperature  of  the  ocean  air  during  winter,  compared 
to  the  inland  atmosph(>re,  is  easily  i)erceptible  when  traveling  from  San 
Francisco  on  the  ocean's  shore,  to  Saci-amento  which  is  eighty-live 
miles  inland.  The  United  States  Weather  l^ureau  records  show  the 
mean  temperature  for  January,  the  mid-winter  month,  to  lie  H  degi-i^es 
higher   in    Ran    Francisco   than    in    Sacramento,    I)ut    the   temperature 


WATER   RESOURCES    OF    CALIFORNIA.  Zi 

changes  of  ocean  winds  traveling  northerly  and  landward  would  be 
still  greater  than  this.  It  thus  comes  about  that  the  rain-producing 
winds  of  California  are  generally  from  the  southwest  and  south.  Flow- 
ing otf  the  Pacific,  where  the  air  has  become  heavy  with  water-vapor 
through  contact  with  the  ocean,  the  winter  winds  traveling  northward 
and  inland,  enter  regions  of  lower  temperature,  and  the  capacity  of  the 
moving  air  to  hold  moisture  is  reduced,  so,  heavy  with  moisture  for 
their  temperature  as  they  leave  the  ocean,  clouds  are  formed  as  the 
winds  progress  inland.  If  the  change  is  sufficiently  pronounced,  the 
v.atery  particles  coalesce  and  are  precipitated  earthward  as  rain,  snow 
or  hail. 

Winds  blowing  from  a  land  area  are  not  favorable  to  precipitation, 
even  though  their  temperature  may  be  reduced  on  entering  a  cooler 
region,  for  the  usual  variation  of  temperature  between  night  and  day 
over  the  continent,  where  the  air  begins  its  movement,  is  greater  than 
ever  the  ocean  and  prohibits  its  being  so  nearly  saturated  with  moisture 
as  it  starts  on  its  journey.  For  this  reason,  in  California  the  southeast- 
erly winds  usually  produce  lighter  showers,  while  southerly  and  south- 
westerly winds  produce  the  heavy  downpours.  Westerly  winds  may 
produce  light  showers  but.  without  northward  travel,  variations  of  tem- 
perature great  enough  to  discharge  large  volumes  of  water  from  the 
atmosphere,  are  not  apt  to  be  experienced.  Similarly,  easterly  and 
especially  northerly  winds  are  dry  and,  except  under  special  local 
circumstances,  they  would  never  undergo  a  lowering  of  temperature 
sufficient  to  cause  precipitation  of  even  a  small  portion  of  their  mois- 
ture. For  a  like  reason,  the  southerly  and  southwesterly  winds  of 
summer,  blowing"  from  oft'  the  cooler  ocean  to  the  warmer  land,  do 
not  experience  a  lowering  of  their  capacity  to  hold  moisture,  so  that  no 
precipitation  occurs.  On  the  contrary,  these  inflowing  winds,  warmed 
by  contact  with  the  land,  may  have  their  water-vapor  holding-capacity 
increased  and  become  dry  winds. 

All  these  air  movements  toward  the  low-pressure  areas,  in  sweeping  iii 
from  long  distances,  are  extensive  as  to  the  areas  traversed.  Impelled 
by  the  same  power  and  rushing  to  the  same  low-pressure  area,  similar 
winds  blow  over  areas  of  thousands  of  square  miles.  In  passing  over 
the  land,  varying  quantities  of  moisture  are  precipitated  along  the  way, 
as  the  winds  are  cooled  to  varying  degrees,  or  deflected  or  diverted  by 
local  topography.  So  rain  gages  in  adjacent  locations  may  register 
ditferent  quantities  of  rain,  all  produced  from  the  same  widespread 
storm.  The  shelter  of  knolls,  of  hills  or  mountains,  or  of  ridges 
or  spurs,  may  lessen  the  quantity  precipitated  on  leeward  areas,  while 
the  more  exposed  regions  may  receive  an  increased  rainfall.  The 
greater  cooling  of  the  air  on  moving  up  slopes  and  arriving  at  higher 
elevations,  usually  increases  the  precipitation  as  well.  Since  these 
v^ariations  in  quantitiy  of  precipitation  vary  with  toj)ography  and 
elevation,  which  are  fixed  in  their  influence  and  unchanged  with  the 
arrival  of  new  storms  in  future  yeai's,  the  precipitation  taking  place  in 
adjacent  areas  and  over  which  the  same  storm  winds  customarily  sweep, 
Avhile  not  alike  in  quantity  falling,  is  quite  similar  in  magnitude  rela- 
tive to  tlie  precipitation  of  other  years.  So  tlie  magnitudt^  of  ]irecipita- 
tion,  relative  to  that  of  other  years,  is  found  to  be  very  nearly  alike 
over  whole  regions,  so  much  so,  that  the  term  "index  of  seasonal  wet- 
ness" has  been   evolved  to  express  this  maunitude  of  the  total   rain- 


28  WATER    UESOUKCES    OF    CALIFORNIA. 

fall  fur  a  season  relative  to  the  magnitude  of  other  seasons,  and  this 
index  has  like  values  over  entire  sections  of  the  state. 

The  numerical  value  for  the  "index  of  seasonal  wetness''  at  any 
rainfall  station,  is  the  total  rainfall  for  tliat  season  expressed  in  per 
cent  of  its  annual  mean.  This  mean  is  the  averajre  value  for  several 
years  of  record,  and  the  nmiiber  of  years  should  hv  extensive  enough 
that  their  average  approaches  a  value,  which  the  rains  of  succeeding 
years  exceed  and  fall  short  of  "m  like  amounts.  The  index  of  seasonal 
wetness,  comi)uted  from  sucii  a  mean,  expresses  the  degree  of  wetness 
of  the  rainfall  experienced  that  season  by  any  locality,  in  terms  of 
their  customary  or  normal  pret-ipitation.  These  indices  for  successive 
years  form  a  series  of  numbers  which  bear  a  redation,  one  to  the  other, 
identical  to  that  of  the  actual  values  of  seasonal  i-ainfall,  but  instead 
of  expressing  volumes  of  water  as  do  the  precipitation  records  them- 
selves, they  ex]n-ess  the  degree  of  normalcy  of  each  season's  rainfall. 
To  conver.t  the  indices  to  actual  volumes  of  water,  they  must  be  multi- 
plied by  the  value  of  the  mean  sasonal  rainfall. 

Plate   I,  "Comparison  of  Index  of  Seasonal  Wetness  in  ^lountain 
and  Valley  Areas,"  illustrates  the  similarity  in  value  of  relative  pre- 
cipitation in  adjacent  areas.     A  mountain  area  in  the  Sierra  Xevadas 
is  here  compared  to  a  portion  of  the  Sacramento  Valley  which,  although 
several  thousand  feet  lower  in  elevation,  is  located  in  the  same  storm 
paths.     The  indices  for  six  stations  of  the  United   States  Weather 
Bureau  in  each  of  these  areas  are  averaged  and  plotted  on  the  diagram. 
To  accentuate  any  cumulative  difference  in  the  values  of  these  compared 
average  indices  for  the  mountain  and  valley  areas,  as  the  years  succeed 
themselves,  they  are  plotted  as  sums;  each  value  plotted  being  the  sum 
of  all  indices  for  its  area,  beginning  with  the  initial  year  and  including 
the  value  of  each  successive  year  up  to  the  one  for  w^hieh  the  value  is 
plotted.     In  originally  expressing'  these  indices  in  per  cent,  each  one 
contains  the  number  100,  w^hich  represents  the  wetness  of  a  year  of 
normal  rainfall ;  the  years  that  had  a  preci])itation  above  normal  are 
represented  by  numbers  gi'eater  than  100;  and  those  that  h:ul  less,  by 
numbers  smaller  than   100.     In  the  diagram,  Plate  I,  the  transverse 
heavy  line  about  midway  between  the  top  and  bottom  lines,  represents 
this  datum  of  100,  and  this  heavy  line  is  intercepted  by  lightly  drawn 
lines  at  right  angles  to  it  in  direction,  one  to  a  year,  on  whicli  are 
plotted   the  successive   accu)nulated   sums  above   or  below   the   datum 
line.     But  since,  in  summing  the  indices  of  successive  years  t:i  obtain 
values  for  plotting  on  this  diagram,  the  adding  into  the  sums  of  the 
value  100  contained  in  every  index  would  serve  no  useful  juirjiose,  all 
the  indices  had  their  numerical   values  decreased  by  subtracting  100 
from  them  before  the  additions  were  made.     This,  in  effect,  makes  the 
genei-al  direction  of  the  lines  on  the  graph,  i>rogress  transversely  acr()S.s 
the  paper  from  left  to  right,  instead  of  continuously  inclining  ujnvard 
as  the  multiple  additions  of  100  would  have  caused  them  to  do.  if  the 
100  had  not  been  first  sul)tracted  from  each  value.     The  sum  j)lotted 
on  each  yearly  line  becomes  gi'eater  than  the  sum  plotted  for  the  pre- 
vious year,  if  the  index  representing  tlu'  intervening  season  is  larger 
than  100;  and  similarly  the  sum  liecomes  less  than  that  plotted  for  the 
)>revious  year,  wh<m  llie  index  of  the  intei-vening  season  is  smaller  than 
100.     So  the  idolled  liiu^s  traverse  the  chart  ])arallel  to  the  datum  line 
when    the   ]>recii)itation    for   the    >-(\ir    is    noi'ui.d,    slope    u]>ward    with

above  normal  season  precipitation,  and  downward  with  subnormal 
precipitation.  The  steepness  of  the  upward  ineliuations  and  the  sharj)- 
uess  of  descent  of  the  downward  slopes,  indicate  the  degree  of  wetness 
compared  to  the  mean  or  normal,  of  these  two  areas.  The  plotted  lines 
pass  above  the  heav}'  datum  line  or  below  it,  as  the  accumulated  precipi- 
tation, beginning  with  the  initial  year,  is  greater  or  less  than  it  would 
have  been  had  all  seasons  for  which  the  indices  are  summed,  been 
normal ;  and  the  passage  across  the  heavy  datum  line  is  witliout  rela- 
tion to  the  normality  of  the  year  in  wliich  the  line  crosses  the  datum. 

These  j)k)tted  lines  on  Plate  I.  one  for  a  mountain  area  and  one  for 
a  vaUey  area  several  thousand  feet  below,  picture  the  secjueuee  in 
values  of  the  indices  for  the  two  areas  as  the  lines  progress  from  loft 
to  right.  The  downward  slope  of  a  section  of  a  line,  where  values  for 
successive  years  continually  plot  lower  and  lower  approaching  the 
bottom  of  the  chart,  indicates  a  period  of  consecutive  years  during 
which  the  precipitation  is  less  than  normal;  in  an  analogous  manner, 
the  oppositely  directed  sectiojis  that  pursue  a  course  continually  directed 
upward,  show  the  occurrence  of  wet  periods.  Of  these  inclined  sections, 
their  length,  distinguished  by  the  number  of  yearly  lines  intercepted, 
represent  the  duration  of  these  periods  and  their  steepness  shows  the 
degree  of  their  departure  from  normal. 

Should  it  be  that  the  magnitude  of  the  precipitation  was  not  propor- 
tional in  these  two  regions  which  are  here  compared ;  that  the  sequence 
of  values  of  seasonal  precipitation  in  the  one  was  not  duplicated  by  a 
like  sequence  in  the  other;  or  that  with  the  appearance  of  a  group  of 
wet  years  in  one  area,  a  group  of  equally  wet  years  did  not  appear  in 
the  other;  then  these  two  lines,  one  representing  a  mountain  region,  the 
other  a  valley  area,  would  have  deviated  from  each  other  as  tliey  cro.ss 
the  chart,  and  as  unlike  rainfall  continued  to  liave  occurred  in  the  two 
regions  during  the  same  years,  the  lines  would  have  departed  wider  and 
wider.  Instead,  the  approximate  coincidence  of  the  two  lines  through- 
out their  entire  course  across  the  diagram,  shows  that  the  slight  numer- 
ical differences  in  values  of  sums,  plotted  for  the  two  areas  in  the 
same  seasons,  are  variables  that  are  wholly  circumstantial  and  are 
greater  or  less  than  zero  without  prefei-ence.  The  close  proximity-  of 
these  two  diagrammatic  lines  as  the  precipitation  o;-cnrrenccs  over  one 
area  are  duplicated  over  the  other  area  several  thousand  feet  lower  on 
the  valley  floor  and  some  fifty  miles  distant,  shows  hnw  widespread 
are  the  rain-producing  meteorological  phenomena  and  how  th.ey  cause 
proportionally  like  events  to  occur  at  widely  sejiarated  places,  diversely 
situated  both  topogi-aphically  and  geographically  and  one  receiving 
almost  twice  the  total  precipitation  of  the  other. 

By  constructing  like  diagrams  to  present  the  cumulative  sums  of  the 
indices  of  seasonal  wetness  for  every  one  of  the  277  rainfall  stations 
that  the  United  States  AV(>ather  Bni-eau  has  maintained  in  California 
for  more  than  ten  yeai's,  the  se(|uence  of  magnitude  of  seasonal  pi'e- 
^•ipitation  relative  to  its  mean,  has  been  compared  over  all  the  state.  In 
so  doing,  it  was  found  that,  althnngh  the  indices  of  wetness  in  all  parts 
of  the  state  tend  toward  like  values,  there  were  groups  into  which  the 
stations  naturally  fell.  By  superimposing  these  lines  in  all  the  various 
l)()ssil)le  combinations  of  station  comparison,  it  was  disdo.sed  that  the 
lines  of  certain  groups  were  in  approximate  coincidence,  wliile  they 
diverged,   often   widely,   from   the  lines  of  other  stations  outside   the

group.  Tvvent}-six  natural  groups  were  so  distinguished,  each  with 
the  diagrammatic  lines  in  the  group  approaching  coincidence  with  the 
mean  line  of  the  grouj),  more  closely  than  they  approached,  with  similar 
coincidence,  the  diagrannnatic  lines  of  the  stations  in  other  groups. 
These  twenty-six  groups,  segregated  solely  by  the  similarity  in  shape 
of  the  diagrammatic  lines  of  adjoining  rainfall  stations,  then,  represent 
the  aggregate  precipitation  records  on  twenty-six  areas,  each  customa- 
rily swept  by  the  same  storms.  The  magnitude  relative  to  the  mean,  of 
the  rainfall  in  successive  seasons  over  each  of  these  areas,  is  alike.  The 
average  index  for  all  the  stations  of  a  group  also  represents,  with  a 
close  degree  of  approximation,  the  magnitude  of  the  precipitation  at 
all  the  stations  within  the  group.  This  average  magnitude  relative  to 
the  mean,  of  the  seasonal  precipitation  over  the  area  represented  by 
each  of  the  twenty-six  groups  of  rainfall  stations,  is  set  forth  in  Table 
1,  "Indices  of  Seasonal  Wetness  for  Twenty-six  Precipitation  Divi- 
sions." These  indices  of  seasonal  wetness  express  this  magnitude  of 
seasonal  precipitation  in  all  parts  of  the  state  for  each  of  the  fifty 
years  tabulated  and  for  each  area  of  the  state  customarily  swept  by  the 
same  storms.

Comparison  of  Station  Precipitation  to  Mean  Sequence  of  Division," 
])resent  diagrammatic  lines  similar  to  those  .just  described,  for  each 
of  two  hundred  and  sixty  United  States  Weather  Bureau  Stations  that 
have  more  than  ten  years  of  record.  These  diagrammatic  lines  are 
superimposed  one  on  the  other,  for  all  the  stations  in  a  group.  Twenty- 
six  plats  are  so  presented  in  these  nine  plates,  one  plat  to  a  group  or 
division  of  the  state,  and  the  mean  diagrammatic  line  for  each  group 
is  shown  thereon  as  a  heavy  black  line.  Each  group  or  division  of  the 
state  has  been  named  for  its  locality  and  labeled  with  a  letter  of  the 
alphabet,  while  each  rainfall  station  bears  a  reference  number.  The 
name  of  each  division  and  its  letter  symbol  are  tabulated  in  Table  1. 

Table  4,  "Alphabetical  List  of  Rainfall  Stations  and  Summary  of 
Precipitation  Data,"  records  every  rainfall  station  used  in  these  com- 
parisons, together  with  its  reference  number,  its  precipitation  division, 
elevation  above  sea-level,  years  of  record,  mean  of  the  years  of  record, 
and  the  fifty  year  mean  obtained  by  proportional  comparison  with  the 
longer  records  at  other  stations  in  the  same  precipitation  division. 

This  table  also  contains  references  to  Tables  5  to  30.  "Records  of 
Precipitation  and  Talile  of  Computed  Indices  of  Seasonal  Wetness  for 
Precipitation  Divisions."  This  series  of  twenty-six  tables,  one  each 
to  a  precipitation  division,  lists  the  names  of  the  rainfall  stations  fall- 
ing in  the  group  within  the  limits  of  each  division.  The  measured 
seasonal  precipitation  is  there  tabulated  and  alongside  is  shown  the 
index  of  seasonal  wetness  computed  from  the  records  of  that  station. 
The  index  is  tabulated  for  each  one  of  fifty  years,  including  those  in 
which  no  precipitation  measurements  were  made.  These  indices  were 
all  obtained  by  dividing  the  seasonal  precipitation,  either  measured, 
or  computed  when  no  measurements  existed,  by  the  mean  seasonal  rain- 
fall for  the  fifty  year  period.  The  rainfall  for  the  years  of  missing 
record  at  each  station  was  computed  through  simple  proportioii,  by  com- 
pariug  it  to  the  rainfall  of  other  stations  in  the  same  group  that  liad

a  greater  imiiiber  of  years  of  rei-ord.  The  precipitaliou  for  the  .seasou 
of  missing  record  in  each  case  was  taken  to  bear  the  same  ratio  to  the 
l)rec'ii)itation  for  the  same  season  at  the  stations  of  longer  record,  that 
the  average  precipitation  for  the  years  of  reconl  at  the  short  time  sta- 
tion bore  to  the  average  precipitation  for  the  same  period  of  years,  at 
all  the  stations  of  longer  record.  The  fifty  year  mean  seasonal  i>re- 
(ipilation  here  nsed  is  the  average  of  the  fifty  seasonal  (puintities  so 
oI)t;iined.  It  includes  all  the  measured  values  as  well  as  those  com- 
puted for  the  years  that  lacked  a  record.  The  extreme  right  hand 
column  of  each  of  these  twenty-six  tables  lists  the  average  value  for 
each  season,  of  the  indices  of  wetness  of  all  the  rainfall  stations 
i)i  the  group.  This  avernge  value  is  the  index  of  seasonal  wetness  for 
tlic  pr(M'i|)iliil  iuii  division  tabulated  in  Table  1,  'Muilex  of  Seasonal 
Wetness  for  Tweiit\'-six  I'l-ei-ipilalion  Divisions,"  and  used  in  cou- 
stnicting  the  diagrammatic  lines  showing  the  secpience  of  precipita- 
tion in  the  division  on   Plates  IT  to  X.

Table  31,  "  Rliseellaneou.s  Precipitation  Records,  U.  S.  Weather 
Bureau,"  tabulates  the  precipitation  for  all  stations  of  the  United 
States  Weather  Bureau  with  more  than  ten  years  of  record,  not  used 
in  the  compilation  of  indices  of  seasonal  wetness.  Excepting  those 
located  in  the  desert  region  in  the  southeastern  corner  of  the 
state,  for  which  no  study  was  made,  Tehama,  Sacramento,  San  Fran- 
cisco, Oakland,  Berkeley,  and  Point  Reyes  are  the  only  ones  omitted. 
Plate  XI,  "Comparison  of  Sequences  of  Precipitation  at  San  Francisco, 
Oakland,  Berkeley  and  Sacramento  with  JMean  Sequence  of  Adjacent 
Precipitation  Divisions,"  shows  why  these  stations  were  not  included 
in  the  study.  Although  having  long  years  of  record,  these  stations 
are  not  like  adjoining  ones.  The  decided  difference  in  shape  of  their 
diagrammatic  lines  from  those  of  adjacent  stations,  of  which  there 
are  many,  and  the  divergence  of  these  lines  from  the  average  lines  of 
adjoining  stations  as  they  cross  the  plat  from  left  to  right,  show  that  the 
seciuence  of  measured  precipitation  from  season  to  season  at  these 
stations  is  out  of  harmony  with  that  at  the  large  number  of  adjacent 
rainfall  stations. 

Th*^  twenty-six  precipitation  divisions  of  the  state,  developed  through 
the  analysis  of  all  the  precipitation  data  of  the  United  States  Weather 
Bureau,  are  delineated  on  Plate  XII,  "Map  Showing  Boundaries  of 
Precipitation  Divisions."  The  location  of  all  the  rainfall  stations  is 
shown  on  this  map  by  red  dots  and  the  number  close  to  the  dot  is  the 
station  reference  number.  On  the  map,  and  at  the  top,  the  names  of  all 
these  stations  are  listed  opposite  the  station  reference  numbers,  which 
are  arranged  in  numerical  order. 

This  map  sets  forth  the  boundaries  of  these  areas  of  the  state, 
twenty-six  in  numl)er,  which  are  swept  by  the  same  storms.  Dissimilar 
in  topography  but  alike  in  l)eing  customarily  traversed  by  the  same 
moisture  laden  winds,  the  land  in  each  area  enjoys  wet  seasons  or  suffers 
droughts,  in  unison.  With  startling  differences  in  the  magnitude  of 
precipitation  at  the  several  stations  within  each  area,  still  their  rela- 
tive magnitude  in  succeeding  years  is  so  much  alike  that  it  can  be 
oxin-essed  quite  accurately  by  one  index  number  for  all  the  stations 
within  the  area.  These  indices,  named  "indices  of  seasonal  wetness" 
show  the  relation  of  the  seasonal  precipitation  to  the  long  time  mean 
for  every  part  of  the  division  and  for  each  year  of  the  past,  and  are 
a  measure  of  the  degree  of  conformity  of  each  season  to  the  mean. 
Seasons  having  indices  greater  than  100  are  wet  years,  and  are  wetter 
the  higher  the  value  of  the  index.  Occasionally,  vears  of  extremely 
heavy  precipitation  have  values  as  high  as  200.  The  dry  years  have 
indices  falling  below  100.  and  extreme  droughts  have  values  of  50  to  60. 

Here  then,  encompassed  within  the  small  limits  of  Table  1,  "Indices 
of  Seasonal  Wetness  for  Twenty-six  Precipitation  Divisions,"  and 
Plate  XII.  "INIap  Sliowing  Boundardies  of  Precipitation  Divisions." 
is  recorded  the  history  of  the  variation  of  seasonal  rainfall  during  the 
l^ast  half  century  and  in  every  i)art  of  the  state.

CHAPTER  III. 


RUN-OFF  FROM  THE  MOUNTAIN  AREA. 

The  water-bearing-  winds  that  traverse  California  during  the  rainy 
winter  season  precipitate  three  Inindred  billion  tons  of  water  annually 
npon  the  surface  of  the  State.  Most  of  this  falls  as  rain  or  snow  upon 
the  mountain  area.  Higher  in  elevation  and  cooler  in  temperature,  the 
mountains  are  more  effective  in  reducing  the  moisture  holding-capacity 
of  the  vapor-laden  ^\dnds  than  are  the  fiat  lands,  so  that  these  winds 
in  rushing  toward  the  low  pressure  areas,  give  up  much  more  water  to 
the  mountains  than  to  the  lower  regions.  This  precipitation,  as  rain, 
strikes  the  surface  of  their  slopes  to  flow  toward  lower  elevations;  as 
snow,  it  mantles  the  earth's  surface  or  collects  in  wind-blown  drifts 
to  await  warmer  temperatures  for  conversion  to  mobile,  liquid  water 
th  it  may  pursue  a  like  downhill  course  toward  the  ocean. 

The  moving  waters,  ever  journeying  to  lower  elevations,  concentrate 
in  the  ravines  and  gullies  toward  which  the  surfaces  slope.  Continually 
enhanced  in  volume  by  confluence  with  the  like  accumulations  in  inter- 
cepted channels,  they  restlessly  pursue  their  downward  course,  follow- 
ing the  most  deeply  cut  depressions  or  the  steepest  g'radients,  mitil 
they  finally  become  engulfed  in  the  earth's  vast  reservoir  of  waters, 
the  ocean.  These  ever-journeying  waters,  falling  on  the  drainage  area 
as  precipitation,  concentrated  on  the  land  surface  as  run-off,  and 
coursing  down  the  water-channels  as  stream-flow,  reach  the  ocean  as 
drainage;  and  so  by  returning  to  the  storehouse  of  w^aters  from  which 
+hey  were  first  vaporized  and  carried  to  the  mountainous  area  by  the 
jioisture  laden  winds,  they  have  completed  their  circuit  of  travel. 

(California's  water  producing  area,  the  moixatains,  although  nearly 
state-wide,  is  not  uniform  in  water  yield.  Influenced  by  the  topog- 
raphy, the  elevation,  and  the  exposure  of  the  divers  localities,  varying 
amounts  of  precipitation  fall  on  the  collecting  areas,  and  the  run-off 
derived  from  it  also  varies  in  a  similar  manner.  Generally,  the  run-oft' 
is  least  from  the  regions  near  the  Mexican  border,  and  greatest  in  those 
northward  areas  of  the  Coast  Range  Mountains  that  are  contiguous  to 
the  Oregon  line.  It  ranges  from  less  than  an  inch  in  depth  over  the 
land  annually  from  the  least  productive  regions  of  the  .south,  to  over 
a  hundred  inches  in  depth  from  the  greatest  water-producing  areas  of 
the  north.  Between  these  two  extreme  regions  separated  by  the  length 
of  the  state,  is  the  water-producing  mountain  area,  three-fifths  the 
surface  of  the  state. 

The  variation  of  run-off  in  the  geographical  divisions  of  this  water- 
producing  area,  however,  is  quite  similar  to  the  variation  in  elevation 
above  sea-level,  for  the  higher  altitudes,  in  being  most  effective  in 
intercepting  and  cooling  the  moisture  laden  winds,  are  recipient  of  the 
largest  amounts  of  precipitation.  The  cold  of  their  great  heights 
precipitates  excess  atmospheric  water-vapors  as  snow,  solid  crystaline 
M^ater ;  while  the  lower  regions,  warmer  in  temperature,  are  recipient  of 
liquid  water  only,  as  rain.    Distinguishable  by  the  form  in  which  the

of  the  vapor-laden  ^^dnds  than  are  the  flat  lands,  so  that  these  winds 
in  rushing  toward  the  low  pressure  areas,  give  up  much  more  water  to 
the  mountains  than  to  the  lower  regions.  This  precipitation,  as  rain, 
strikes  the  surface  of  their  slopes  to  flow  toward  lower  elevations;  as 
snow,  it  mantles  the  earth's  surface  or  collects  in  wind-blown  drifts 
to  await  warmer  temperatures  for  conversion  to  mobile,  liquid  water 
tb  it  may  pursue  a  like  downhill  course  toward  the  ocean. 

The  moving  waters,  ever  journeying  to  lower  elevations,  concentrate 
in  the  ravines  and  gullies  toward  which  the  surfaces  slope.  Continually 
enhanced  in  volume  by  confluence  with  the  like  accumulations  in  inter- 
cepted channels,  they  restlessly  pursue  their  downward  course,  follow- 
ing the  most  deeply  cut  depressions  or  the  steepest  g'radients,  until 
they  Anally  become  engulfed  in  the  earth's  vast  reservoir  of  waters, 
the  ocean.  These  ever- journeying  waters,  falling  on  the  drainage  area 
as  precipitation,  concentrated  on  the  land  surface  as  run-ofl',  and 
coursing  down  the  water-channels  as  stream-flow,  reach  the  ocean  as 
drainage;  and  so  by  returning  to  the  storehouse  of  waters  from  which 
+hey  were  first  vaporized  and  carried  to  the  mountainous  area  by  the 
I  loisture  laden  winds,  they  have  completed  their  circuit  of  travel. 

C'alifornia's  water  producing  area,  the  mountains,  although  nearly 
state-wide,  is  not  uniform  in  water  yield.  Influenced  by  the  topog- 
raphy, the  elevation,  and  the  exposure  of  the  divers  localities,  varying 
amounts  of  precipitation  fall  on  the  collecting  areas,  and  the  run-ofl:' 
derived  from  it  also  varies  in  a  similar  manner.  Generally,  the  run-off 
is  least  from  the  regions  near  the  Mexican  border,  and  greatest  in  those 
northward  areas  of  the  Coast  Range  Mountains  that  are  contiguous  to 
the  Oregon  line.  It  ranges  from  less  than  an  inch  in  depth  over  the 
land  annually  from  the  least  productive  regions  of  the  .south,  to  over 
a  hundred  inches  in  depth  from  the  greatest  wiater-producing  areas  of 
the  north.  Between  these  two  extreme  regions  separated  by  the  length 
of  the  state,  is  the  water-producing  mountain  area,  three-fifths  the 
surface  of  the  state. 

The  variation  of  run-off  in  the  geographical  divisions  of  this  water- 
producing  area,  however,  is  quite  similar  to  the  variation  in  elevation 
above  sea-level,  for  the  higher  altitudes,  in  being  most  effective  in 
intercepting  and  cooling  the  moisture  laden  winds,  are  recipient  of  the 
largest  amounts  of  precipitation.  The  cold  of  their  great  heights 
precipitates  excess  atmospheric  water-vapors  as  snow,  solid  crystaline 
water ;  while  the  lower  regions,  warmer  in  temperature,  are  recipient  of 
liquid  water  only,  as  rain.    Distinguishable  by  the  form  in  which  the 


46  WATER  RESOURCES   OF   CALIFORNIA. 

waters  are  ])recii)italed  upon  them,  the  surface  of  the  State  may  be 
divided  into  throe  regions.  These  regions  diflFer  in  their  altitude  above 
sea-Un'el.  The  U)\vest  of  these  receives  its  precipitation  entirely  as  rain, 
and  the  highest  as  snow.  Intermediate  between  the  two,  precipitation 
occurs  as  snow  or  at  other  times  as  rain.  Water  production  in  large 
volumes  is  confined  to  the  two  higher  regions  which  occupy  two-fifths 
of  the  total  area  of  the  state. 

The  most  elevated  of  the  two  great  water-producing  regions  lies 
al)Ove  altitudes  of  5000  feet,  and  comprises  the  peaks  and  slopes  of  the 
highest  mountains  and  the  highland  fiats  and  meadows.  Through 
receiving  a  greater  precipitation  and  almost  wholly  in  the  form  of 
snow,  this  region  yields  the  largest  volumes  of  Avater  and  sustains  the 
llow  in  the  strofinis  for  a  more  protracted  period  of  time  than  do  the 
other  portions  of  the  State.  This  water-producing  expanse  of  high 
mountains,  22,400,000  acres  in  extent,  lies  between  the  5000  foot  con- 
tour and  its  highest  elevation,  the  tip  of  Mount  Whitney,  United 
States'  culniinating  peak,  14,500  feet  above  the  sea.  ]Most  of  this 
elevated  region  lies  in  the  Sierra  Nevada  ^Mountains,  between  Tehachapi 
Pass  and  Mount  Shasta.  Olher  portions,  far  less  extensivf;,  lie  in  the 
Coast  Mountains  between  Clear  Lake  and  the  Oregon  boundary,  and 
small  areas  lie  in  the  mountains  south  of  the  Tehachapi  Pass. 

Tne  precipitation  on  these  areas  is  almost  entirely  snow,  and  this, 
beginning  earlier,  extends  throughout  the  winter  and  continues  later 
into  the  spring  months  than  it  does  in  other  regions.  Through  the 
dead  of  Avinter  the  entire  surfac(>  is  clothed  in  a  mantle  of  snow,  and 
huge  drifts  collect  in  the  more  sheltered  recesses  of  the  mountain 
flanks  to  smooth  their  outlines  and  throw  the  protruding  rocks  into 
high  relief.  Nestling  among  the  crags  and  crests  and  filling  pockets 
eroded  in  their  sides,  are  sixty-five  glaciers.  These  bodies  of  perennial 
ice  grow  in  size  during  the  winter  months,  through  the  consolidation 
of  the  snow  fallii^g  and  drifting  on  them,  but  shrink  during  the  sununer 
and  deplete  their  mass,  yielding  the  melted  ice  and  snow  waters  that 
give  source  to  the  streams  which  issue  from  them.  The  waters  of  this 
region  remain  congealed  until  the  summer  warmth  melts  them,  and  so, 
retarded  in  their  run-off.  they  do  not  reach  the  stream  channels  until 
May,  June  and  July.  Since  large  amounts  of  heat  are  required  to 
release  these  waters  from  their  chill  bondage,  the  run-ofl:  from  these 
areas  does  not  contribute  to  large  floods,  but  rather  enhances  the 
stream  flow  with  fair  uniformity  during  the  melting  period,  fiuctufding 
with  the  alterations  of  warm  and  cool  weather. 

Below  these  hi'jbland  regions,  but  more  than  2500  feet  above  the 
.sea.  is  an  area  2:^700, ()()()  acres  in  extent,  mountainous  and  rugged  of 
structure,  and  comprising  about  one-half  the  upland  area  of  the  state. 
This  expanse  includes  the  eminences  of  foothills,  the  .secondary  ridges, 
the  sloping  sides  of  major  mountain  chains,  the  smaller  ranges  in  theii- 
entirety,  and  most  of  the  plateaus  and  mountain  valleys  of  California. 
The  precii^itation  over  these  lands  oecnrs  lioth  as  snow  and  rain,  thougli 
the  mantle  of  snow  is  of  but  short  dnration.  Elevated  and  genei-ally 
receiving  a  large  precipitation,  th(^  wide  expanses  of  this  region  yield 
large  volumes  of  run-off.  Sonu'times  melting  with  subsequent  warm 
rains,  the  snows  of  this  region  join  with  the  run-off  of  heavy  rain- 
storms and  swell  the  streams  to  extreme  flood  height.  But  since  most 
of  the  pi-eeipit.'ition  f.dls  as  rain,  run-off  usnally  follows  ((uiekly  after

tilt'  stoi'ius.  Streams  attain  their  tluod  stage  during  or  shortly  after 
the  heavier  do\viij)oiirs.  Most  of  the  ruii-ott'  oecurs  duriiig  the  mouths 
of  heavy  rain,  Deeember,  January,  February  and  March,  but  the  flo^v 
is  nsnally  well  sustained,  nevertheless,  from  lesser  showers  and 
drainage  from  water-soaked  portions  of  the  region,  during  April  and 
I\Iay. 

The  third  region,  entirely  below  elevation  2500,  includes  the  low-lying 
fiat  lands  of  the  State,  the  foothills  and  rolling  slopes  of  the  marginal 
lands,  and  the  lower  mountains.  ]Much  of  this  area  is  agricultural. 
J'].xeept  for  occasional  lig-ht  snow  storms,  the  precipitation  falling  here 
is  entirely  rain.  Receiving  a  lighter  precipitation  and  being  soil 
covered  and  less  steep  of  slope,  this  region  contril)utes  the  least  to  the 
State's  run-off.  Its  flat  lands,  lacking  the  surface  inclination  to  put 
the  water  in  motion,  largely'  absorb  the  rains  falling  upon  them,  or 
detain  them  in  pools  and  puddles  or  in  the  saturated  top-soil,  to  be 
evaporated  back  into  the  atmosphere.  Only  during  extremely  heavy 
downpours  of  infrequent  occurrence,  do  the  flat  lands  contribute  run- 
oft'  to  the  stream  channels.  The  rains  fallinir  on  the  foothill  and  moun- 
tainous areas  of  this  region,  however,  usually  find  their  way  quickly 
into  the  stream  channels  after  the  ground  s^^rface  has  become  wet. 
But  with  a  third  of  the  seasonal  rainfall  often  required  to  soak  the 
surface  soil  before  appreciable  run-off  may  occur,  the  contribution  to 
stream  flow  from,  this  area  is  much  less  than  from  the  higher  regions, 
it  does  not  begin  until  mid-\A'inter,  and  is  confined  principally  to  the 
months  of  January,  February  and  March.  JMost  of  the  run-off  from  this 
lower  region  takes  place  ou  lands  too  low  in  elevation  for  tlie  shed 
waters  to  be  caught  in  mouiitain  reservoirs  and,  being  of  short  duration 
and  coming  at  times  when  all  the  agricultural  lands  are  soaked  with 
water,  is  of  little  value,  but  rather  it  is  an  inconvenience,  especially 
on  the  flats,  where  often  the  construction  of  flood  control  or  drainage 
vrorks  is  required  to  relieve  farming  lands  of  a  surfeit  of  water 

The  storms  traversing  California  precipitate  varying  quantities  of 
water  upon  all  of  these  regions,  but  in  each  area  a  portion  only  of  the 
falling  waters  reach  the  stream  channels ;  the  rest  is  dissipated  through 
evaporation  to  the  atmosphere.  This  division  of  waters  takes  place  as 
soon  as  precipitation  starts  and  continues  throughout  the  entire  course 
of  the  water  movement.  Moisture  is  evaporated  from  the  falling  par- 
ticles of  rain  or  snow,  from  the  surface  of  pools  or  puddles,  or  snow 
fields,  and  from  wetted  soil  areas.  Water  is  also  vaporized  from  the 
vegetation  that  groM^s  on  the  watershed  slopes.  Much  of  the  water  that 
wets  the  surface  soils  is  absorbed  by  the  root  systems  of  vegetation  so 
tliat  where  trees,  bushes  and  undergrowth  are  dense,  large  volumes  of 
water  are  vaporized  into  the  atmosphere  through  transpiration  from  1hf 
])lant-surfaces.  Evaporation  from  fallen  snow  may  also  l)e  lar-ge,  as  it 
oi'ten  lies  upon  the  ground  for  months,  exposing  vast  surfaces  from 
which  va])or  may  enter  the  atmosphere.  Even  while  the  run-off  is 
collecting  in  the  stream  channels,  and  continuing  throughout  the  river's 
course,  additional  fractions  of  these  waters  are  dissipated  through 
evaporation.  The  aggregate  precipitation  which  may  be  returned  to 
the  atmosphere  without  becoming  stream  flow  in  the  lower  reaches  of 
the  channels,  may  therefore  be  as  small  as  one-fourth  or  as  large  as 
thrce-foui'ths  of  the  total,  according  to  the  contingencies  of  the  season's

weather  jkkI  the  cireuinstanees  of  t()pograi)hy  and  geology  oi'  the  area 
upon  which  it  falls. 

p]xcept  as  it  falls  on  frozen  or  non-absorbent  surfaces,  precipitation 
upon  strikijig  the  earth  must  first  moisten  its  top-covering,  and  it  is 
only  after  this  has  become  saturated  that  water  gathers  on  th(!  surface 
to  journey  down  the  slopes  of  the  catchment  area.  The  first  rains  of 
the  season,  less  continuous  and  less  intense,  are  usually  taken  up  in 
Avetting  the  surface  upon  which  they  fall,  and  run-off  occurs  only 
after  several  inches  of  moisture  have  been  precipitated.  Collecting 
in  jiuddles  and  pools  or  moving  down  the  slopes  in  streamlets,  some  of 
the  run-off  trickles  into  seams  and  cracks  of  the  mountains'  rocky 
structure  while  other  quantities  are  absorbed  by  pervious  soil  cover- 
ings. Advancing  by  the  attractions  of  gravity  and  capillarity  and 
filling  the  pores  and  interstices  of  the  earth's  crust,  this  percolating 
moisture  penetrates  to  great  depths.  It  finds  its  way  into  the  rocks, 
working  slowly  through  the  seams  and  along  the  faults,  sometimes 
penetrating  to  the  heart  of  the  mountainous  structure.  Although 
usually  a  small  portion  of  the  total,  these  percolating  waters  are 
especially  valuable  to  man  in  their  reappearance  at  lower  elevations 
as  perennial  springs  to  moisten  meadow  lands  or  to  increase  the  waning 
summer  flow  of  brooks  and  streams.  For  these  tardy  waters,  in  penetrat- 
ing the  subsurface  regions  and  pursuing  a  more  dilatory  underground 
course,  wet  the  beds  of  the  stream  channels  the  year  round  and  furnish 
all  or  a  large  part  of  the  dry  season  flow:  they  fill  the  subterranean 
gravels  and  reservoirs,  and  are  the  principal  wiaters  available,  except- 
ing in  lakes  and  reservoirs,  when  the  great  volumes  of  run-off  that 
pass  in  flood  flows  have  subsided.  They  thus  carry  over  volumes  of 
w^ater,  for  deferred  use  during  the  hot,  dry  summers,  that  would  other- 
wise pass  down  the  water  channels  at  a  time  when  not  needed.  The 
aggregate  run-off  from  all  these  regions,  however,  appears  in  the 
stream  channels  in  fluctuating  flows  having  a  striking  similarity  to  the 
periodic  occurrence  of  seasonal  precipitation  in  California.'  Plate 
XIII,  "Characteristics  of  Run-oft'  from  California  Mountains,"  pre- 
sents the  hydrographs  of  five  streams,  each  typical  of  a  separate  sec- 
tion of  the  State.  These  hydrograplis  show  tlie  run-oft'  in  each  of  the 
five  streams,  month  by  month,  for  a  year  of  maximum  flow  and  for 
one  of  mininunu  flow,  as  well  as  the  hydrograpli  of  the  mean  monthly 
flow  of  all  tlie  years  of  record.  For  convenience  of  comparison,  these 
hydrograpiis  arc;  plotted  to  show  the  monthly  run-oft'  in  per  cent  of  the 
annual  mean.  Tlie  hydrographs  show  that  in  all  streams  of  the  State, 
the  l)ulk  of  tlie  run-oft'  occurs  during  the  winter  months,  with  meagre 
quantities  flowing  in  the  middle  and  late  sununer.  The  extreme  varia- 
tion between  the  run-off  of  the  maximum  and  minimum  years,  shows 
the  wide  limits  between  whicli  the  sea.sonal  run-oft'  occurs  in  succes- 
sive seasons,  and  how,  in  the  minimum  year,  the  usual  scanty  sunnuer 
flow  is  much  reduced,  and  tliat  this  takes  place  much  earlier  in  the 
season.  In  general,  tlie  water-production  of  very  wet  seasons  may  be 
as  great  as  four  times  that  of  the  years  of  drouth;  the  average  season 
producing  about  one-half  the  run-off  of  maximum  years;  and  of  all 
the  water  which  wets  the  stream  cliannels  of  the  State,  only  one-sixth 
flows  during  the  five  months  of  August  to  December,  and  but  one- 
third  during  May,  June  and  July,  while  one-half  of  all  the  waters

course  down  the  stream  ehannels  to  empty  into  the  ocean  during  the 
four  months  of  January,  February.  ]\Iareh  and  April. 

This  run-off,  in  draining  from  the  mountains,  concentrates  at  the 
lowest  parts  of  the  many  topograpliic  basius  comprising  their  vast 
expanse.  For  convenience  of  study,  the  smallest  of  these  have  been 
united  in  groups,  and  Plate  XV,  "Map  Showing  Boundaries  of  Drain- 
age Basins,"  delineates  the  boundaries  of  these  drainage  basins  or 
groups  of  minor  basins.  Eaeli  basin  bears  a  number  on  this  map 
referring  to  a  table  at  the  side,  which  gives  the  name  of  the  stream 
draining  it,  or  the  group  of  small  basins. 

Table  32,  "Drainage  Areas  of  California,"  presents  a  detailed 
enumeration  of  the  areas  in  all  these  drainage  basins.  These  are 
arranged  in  the  table  in  the  order  of  their  geographic  location, 
grouped  in  six  large  topographic  divisions  of  the  State.  In  addition 
to  the  total  area  in  each  basin,  the  area  draining  into  each  tributary 
stream  is  also  given,  as  well  as  the  total  area  draining  to  the  point  of 
confluence  of  each  tributary  with  the  main  stream. 

The  water  production  of  all  these  areas  has  been  determined  and, 
of  the  total  run-oif  from  this  52,000,000  acres,  two-thirds  passes  down 
the  channels  of  the  three  largest  rivers  of  the  State,  the  Sacramento, 
the  Klamath  and  the  San  Joaquin.  One  half  of  the  remaining  waters 
flow  in  the  six  next  largest  streams. 

The  State's  total  water  production  sufficient  in  volume  to  cover 
73,000.000  acres  one  foot  in  deptli,  is  nearly  one-half  (forty-eight  per 
cent)  derived  from  the  western  slope  of  the  Sierra  Nevada  Mountains. 
This  runs  oft'  to  join  the  two  large  rivers  of  the  State,  the  Sacramento 
and  San  Joaquin.  The  eastern  slope  of  the  Sierras  produces  only  one- 
tenth  as  much  as  the  western,  or  five  per  cent  of  the  total  waters  of  the 
State.  Similarily,  the  Coast  Range  ^Mountains  shed  nine-tenths  of  their 
run-off  on  the  western  side,  but  their  total  production  is  slightly  less 
than  that  of  the  Sierras,  being  forty-five  per  cent  of  that  for  the  whole 
State.  The  remaining  two  per  cent  of  the  total  waters  of  the  State 
runs  oft'  the  mountains  south  of  the  Tehachapi  Pass  and  this  is  likewise 
apportioned,  nine-tenths  to  the  western  slope  and  one-tenth  to  the 
eastern. 

These  waters,  copious  enough  to  submerge  California's  agricultural 
lands  to  a  depth  of  three  and  one-quarter  feet  each  year,  are  shed  from 
mountain  slopes  replete  with  moisture,  to  rush  through  canyons  and  to 
course  by  agricultural  lands  of  the  valleys  where  they  would  be  invalu- 
able for  irrigation  if  the  flow  occurred  during  the  dry  sea.son.  But 
de^'ived  from  precipitation,  the  run-oft'  closely  follows  the  storms  and 
culminates  during  the  rainy  season  or  shortly  thereafter,  and  these 
waters  largely  flow  past  the  farming  lands  while  they  are  surfeited 
with  moisture  from  the  winter  rains,  to  pass  into  the  ocean  unused.

MEAN   SEASONAL  RUN-OFF   FROM   THE  MOUNTAINS. 

Varying  from  the  rush  of  winter '.s  inundating  tioods  to  the  meagre 
flow  of  suunner  waters  that  exude  from  the  pores,  seams  and  creviees, 
or  shallow  earth  or  gravel  covering  of  the  mountain  structures,  the  run- 
off from  the  mountainous  areas  of  the  State  concentrates  in  stream 
channels,  usually  in  a  continuous  flow  but  capriciously  periodic  in 
volume.  In  fluctuating  annually  v;itli  California's  wet  and  dry 
seasons,  the  precipitation  of  meteoric  waters  to  the  earth  not  only 
furnishes  volumes  of  water  to  the  streams  at  yearly  intervals,  but, 
wave-like,  the  run-off  during  each  season  journeys  to  regions  of  lower 
altitude,  swelling  the  stream  channels  subsequent  to  each  culmiiuition 
in  intensity  and  dwindling  with  each  cessation  of  rainfall.  These 
surface  waters  moving  down  the  stream  channels,  are  a  concentration 
of  precipitation  that  has  fallen  on  drainage  basins  many  times  tlie 
areas  of  the  stream  beds,  so  that  their  gathering  in  the  constricted 
channels  accentuates  the  varying  intensities  of  precipitation  with  wave- 
like swells  in  the  flowing  streams. 

These  waves  move  down  the  stream  channels  as  long,  slim  wedges 
of  water  each  sliding  on  a  base  of  length,  many  times  its  height.  The 
downstream  toes  of  these  wedges  are  the  first  storm-waters  which  find 
their  way  into  tlie  channels,  and  the  climax  in  intensity  of  run-oif 
forms  their  apex-height,  Avliile  their  upstream  edges  are  the  la.st  of  the 
storm's  waters  draining  off  the  collecting  areas.  The  inclination  of 
their  advancing  fronts  increases  with  the  rapidity  of  arrival  of  the 
culminating  intensity  of  precipitation,  and  the  apex-height  of  a  wedge 
is  proportional  to  this  culminatins:  intensity  and  the  base-length  is  pro- 
portional to  the  duration  of  prei-ipitation.  In  passinir  down  the  water 
channels,  these  wedges  have  their  speed  of  movement  retarded  by  the 
friction  of  sliding  on  the  bottom  and  sides  of  the  water  courses.  With 
increasing  roughness,  the  advancing  front  of  the  wedge  becomes  steeper 
and  steeper  as  it  progresses  downstream  and  the  faster  moving  waters 
of  the  apex-height  rush  and  tumble  onward  to  pile  up  over  the  toe- 
water.s  of  the  wedge  struggling  in  their  shallower  depth  to  make 
progress  down  the  rough  stream  bed.  Thus,  in  extreme  instances, 
"walls  of  water"  appear  in  routrh  channels  of  steep  slope  after  sharp, 
heavy  down-pours. 

A  new  wedge  being  launched  with  each  fluctuation  in  intensity 
f)f  precipitation  during  a  .storm,  and  with  each  new  storm,  the  seasonal 
flow  occurring  in  the  state's  streams  is  composed  of  many  wedges  of 
water  sliding  down  toward  the  ocean:  some  closely  superimposed  on 
the  rearward  slopes  of  preceding  wedges,  others  separated  by  wide 
intervals  of  time,  and  all  having  apex-heights  and  lengths  of  ba.se 
whose  magnitude  range  between  wide  limits.  Increasing  variety  is 
also  given  to  the  size  and  sequence  of  successive  water- wedges  by  the 
vastly  innumerable  meteoric  occurrences  that  enhance  or  restrict  the 
portion  of  the  tot;il  jdvcipitatiou  reaching  the  stream  channels.     P^all-

iiig  as  rain,  on  water-soaked  earth  precipitation  quickly  fills  the  stream 
channels  but,  falling  on  mountain  covering  parched  by  sunshine  or  dry 
winds  of  preceding  days,  lesser  portions  of  the  total  precipitation 
rc^ach  them  and  that  more  slowly.  Falling  as  snow,  but  little  or  none 
of  the  precipitation  may  innnediately  find  its  Avay  iuto  streams  but 
rather  may  be  held  in  banks  and  drifts,  or  in  fields  of  ice  or  snow, 
until  later  warm  rains  or  the  melting  summer  sun  releases  it  to  start 
on  its  oceanward  journey.  !So,  the  chaotic  sequence  of  rain,  snow  or 
hail,  winds  and  storms,  or  clouds  or  sunshine,  with  their  changeable 
intensities  and  manifold  durations,  produce  successive  waves  of  flow 
in  the  stream  channels  of  infinite  variation.  The  average  rate  at 
which  the  volumes  of  water  in  these  multiformed  waves  or  water- 
wedges  course  down  the  stream  channels  in  any  season,  including  the 
dwindling,  diminutive  sunmier  flow  after  precipitation  has  ceased  or 
the  season's  snow  is  larg(>ly  melted,  is  called  the  mean  flow  of  the 
stream  for  the  season. 

This  mean  flo^w  for  a  season,  while  comprised  of  many  variable  wave- 
like rushes  of  water,  is  nevertheless  above  all,  distinguished  through- 
out California  by  its  marked  periodic  characteristic  which  recurs  regu- 
larly each  year.  Stream  flow,  derived  from  precipitation,  varies  in 
volume  following  an  annual  cycle  much  like  that  of  the  rains  with 
tlieir  distinctly  wet  season  and  equally  pronounced  dry  season.  Plate 
XIII,  "Characteristics  of  Run-off  from  California  Mountains,"  pre- 
sents the  average  flow,  month  by  month,  for  five  typical  (California 
streams.  The  monthly  flow  of  each  stream  being  expressed  on  this 
plat  in  per  cent  of  the  mean  annual  flow,  permits  the  five  graphs  to  be 
compared,  and  their  singular  likeness  in  shape  for  not  only  the  mean 
year,  but  also  for  the  year  of  maximum  and  the  year  of  minimum  run- 
off, well  illustrates  the  annual  cyclic  characteristic  of  the  run-off  from 
the  state's  mountain  area. 

The  general  semblance  of  shape  of  the  hydrographs  of  the  many 
streams  of  the  State,  which  are  exemplified  by  those  of  the  five  typical 
streams  on  Plate  XIII,  is  given  variety  by  minor  irregularities  caused 
principally  by  the  geographical  position  of  the  catchment  area  and  its 
elevation  above  sea  level.  The  drainage  basins  sheltered  by  mountain 
ranges  likewise  those  of  lower  elevation,  in  receiving  a  smaller  precepi- 
tation,  have  a  greater  proportion  used  in  wetting  their  surface  cover- 
ing so  that  run-oft'  does  not  follow  precipitation  so  quickly,  especially 
ill  early  winter,  as  on  the  more  exposed  and  elevated  areas.  However, 
in  the  very  high  altitudes,  the  snowfall  remains  congealed  in  banks 
and  drifts  until  the  occurrence  of  melting  temperatures,  so  that  much 
of  the  precipitation  on  such  drainage  areas  does  not  run  off  until 
several  months  after  its  fall,  and  it  is  only  in  stream  channels  drain- 
ing these  areas  high  in  elevation  or  those  of  extensive  area  that  fiow 
persists  in  large  volume  for  an  interval  subsequent  to  the  cessation  of 
the  winter's  storms;  but  the  fiow  in  all  streams  soon  diminishes  with 
the  ending  of  the  wet  season  and  the  coming  of  the  period  during  which 
no  moisture  is  precipitated  on  the  catchment  area,  and  reaches  the  low 
flow  generally,  by  the  first  of  August.  This  extreme  depreciation  in 
volume  of  flow  down  the  stream  channels  of  the  state  during  the  late 
sunnner  is  statewide,  and  is  the  characteristic  of  the  annual  stream 
flow  c.ycle  in  California  equally  marked  to  the  usual  great  increase  in 
volume  of  flow  during  the  mid-winter  and  .spring  months. 


52  WATER  RESOURCES   OF   CALIFORNIA. 

Seasons  of  heavy  precipitation  as  well  as  of  light  precipitation  have 
water  running  down  the  stream  channels  with  this  same  general 
periodic  variation  in  volnme,  but  the  total  volume  is  widely  different 
in  succeeding  years.  The  exceedingly  great  variety  of  sequences  of 
rain  or  snow,  winds,  and  clouds  or  sunshine,  tlieir  differing  intensities 
and  uneven  durations  in  each  winter  season,  all  combine  in  divers 
relations  to  make  each  season's  run-off  variant.  In  this  irregularly 
varying  volume  of  total  seasonal  run-off,  that  of  extremely  wet  years 
may  be  four  to  six  times  as  large  as  in  seasons  of  small  run-oft'  and 
the  recurring  order  of  sequence  of  the  waves  of  run-off  may  never  be 
twice  alike  as  the  years  succeed  themselves. 

The  average  or  mean  seasonal  flow  of  any  drainage  basin  is  the 
average  value  of  this  variable  seasonal  run-off'  and  is  an  expression 
for  the  water-yield  of  drainage  basins.  That  this  expression  may 
truly  represent  the  average  water-production,  it  is  requisite  that  a 
suftieieutly  large  number  of  years  of  record  should  be  grouped  for 
averaging,  that  the  extreme  irregularity  in  the  fluctuation  of  successive 
seasonal  values  may  be  suppressed ;  for  the  mean  value  obtained  from  a 
small  number  of  years  of  record  may  alter  as  additional  annual  records 
are  included  in  the  group  for  which  the  average  is  taken.  A  true 
expression  of  the  water-yield  will  therefore  include  so  many  years  in 
the  average,  that  the  inclusion  of  additional  years  will  not  greatly 
change  the  mean  value.  However  desirable  it  may  be  to  encompass 
long  periods  of  time  in  this  determination  of  the  mean  seasonal  volume 
of  water  running  down  the  stream  channels,  the  number  of  years  of 
record  available  is  limited  by  the  years  during  which  measurements  of 
the  flow  in  the  streams  have  been  made. 

The  United  States  Geological  Survej^  through  its  Water  Resources 
Branch  began  the  measurement  of  flow  in  California  streams  as  early 
as  1894,  but  observations  of  flow  were  made  only  on  the  larger  streams 
and  not  very  many  gaging  stations  were  established  and  maintained 
prior  to  1908.  In  this  year,  regular  measurements  were  being  made  on 
fifty-five  streams  of  the  State.  Since  1908.  this  numl)er  has  been 
increased  to  more  ithan  200  stream  gaging  stations  regularly  maintained 
at  the  present  time,  and  some  records  are  available  at  about  500 
stations.  Table  33,  "Publications  of  the  United  States  Geological 
Survey  Containing  California  Stream  Flow  Data,"  sets  forth  the 
references  to  all  these  data  on  stream  flow  observations.  In  addition 
to  the  Suiwey's  gagiugs,  there  are  many  records  of  flow  in  various 
streams  throughout  the  State  that  have  been  made  by  parties  other 
than  the  United  States  Geological  Survey,  but  most  of  the  observations 
made,  either  appear  in  the  pul)li('a1i()ns  of  the  Survey,  or  the  chronicles 
are  of  such  sliort  duration  that  they  are  of  small  utility. 

The  years  of  stream  flow  record  at  each  of  these  gaging  stations  is 
graphically  portrayed  on  Plate  XVI,  "Stream  Measurements  in  Cali- 
fornia by  United  States  Geological  Survey."  Here  the  black  cross- 
bars, opposite  the  name  of  each  gaging  station,  are  drawn  transverse 
to  the  lines  that  extend  from  the  top  to  the  bottom  of  the  page,  one 
to  each  year.  The  transverse  bars,  in  intercepting  the  yearly  lines, 
present  pictorially  the  ]ieriods  of  years  through  which  stream  gaging 
records  have  been  maintained  at  every  station.  The  longer  bars,  in 
intercepting  a  larger  iniinbci-  of  yearly  lines,  represent  a  longer  period 


WATER   RESOITRCES   OF   CALIFORNIA.  53 

of  record  than  the  shorter  bars,  and  the  years  of  the  calendar  during 
which  the  stream  gagings  were  made  are  denoted  at  the  extremities  of 
the  intercepted  yearly  lines.  ITpon  scanning  the  columns  of  years  on 
this  plate,  it  may  be  observed  that  only  sixteen  records  comprise  a 
period  of  more  than  twenty  years  and  that  the  longest  is  twenty-eight 
years.  It  is  also  noticeable  that  there  are  a  large  number  of  records 
from  ten  to  fifteen  years  in  length. 

The  vicissitudes  of  precipitation,  and  of  the  meteoric  phenomena 
which  determine  the  amount  of  water  that  will  run  off  a  collecting 
area  when  precipitation  falls  upon  it,  are  too  great  for  it  to  be  probable 
that  these  measurements  covering  but  little  more  than  a  decade,  would 
include  years  representative  of  all  possible  values.  Their  average, 
therefore,  would  not  truly  express  the  mean  annual  water-production 
of  their  drainage  area.  That  greater  numbers  of  values  of  seasonal 
fluctuation  might  be  included  in  the  groups  to  be  averaged,  resort 
was  had  to  the  chronicles  of  precipitation  which  extend  over  many 
more  years  than  the  measurements  of  stream-flow.  The  United  States 
Weather  Bureau  has  maintained  precipitation  gages  at  one  hundred 
and  fourteen  stations  for  more  than  thirty  years,  at  sixty-two  stations 
for  more  than  forty  years,  and  the  records  of  sixteen  stations  extend  to 
fifty  years  while  three  comprise  a  period  of  over  seventy  years.  Besides, 
there  are  many  more  ^^dth  records  less  than  thirty  years  in  length. 
Of  those  greater  than  ten  years,  there  are  two  hundred  and  seventy- 
four. 

Plate  XVII,  "Precipitation  Records  of  the  United  States  Weather 
Bureau,"  depicts  graphically  the  years  comprised  in  the  record  of  each 
station  and  when  it  began.  The  continuance  of  these  measurements 
through  the  years  is  shown  by  means  of  black  bars  opposite  the  name 
of  the  station  at  which  they  were  made  in  a  manner  similar  to  the  dis- 
play of  stream  gaging  records  on  Plate  XVI.  These  bars  extend 
transversely  across  the  page  from  left  to  right  and  mark  between 
their  extremities  on  the  intercepted  yearly  lines,  the  interval  during 
which  the  precipitation  observations  were  made. 

Since  the  origin  of  all  stream  flow  is  in  the  precipitation  on  the 
drainage  areas,  its  annual  volume  bears  a  relation  to  the  annual  volume 
of  precipitation.  However,  the  proportion  of  the  precipitation  reach- 
ing the  water  channels  is  not  always  the  same.  In  years  of  many  light 
showers,  especially  if  drying  winds  blow  during  the  intervals  between 
them,  a  greater  fraction  of  the  total  evaporates  back  to  the  atmosphere 
than  in  years  of  more  concentrated  precipitation  and  of  dark,  dull  days 
separating  the  storms.  Evaporation  from  snow  fields  may  be  great  if 
weather  conditions  favor  it  because  of  their  vast  areas  exposed  to  the 
drying  atmosphere,  and  it  is  apt  to  be  greater  if  the  arrival  of  melting 
temperatures  is  deferred  by  a  long  winter  season.  Also,  the  division 
of  the  precipitation  between  stream  flow  and  water  that  never  reaches 
the  drainage  channels,  is  influenced  by  the  porosity  of  the  earth's  crust 
and  thf>  ease  with  which  precipitation,  striking  its  surface,  may  perco- 
late to  depths  beyond  the  reach  of  vegetation  or  of  the  capillary  powers 
of  tlie  soil  to  bring  it  back  again  to  be  evaporated  to  the  atmosphere. 
But  the  waters,  which  sink  into  the  earth's  surface-cover  to  follow  the 
minute  conduits  formed  by  connecting  pore  spaces  in  soils  or  gravels 
or  to  traverse  the  devious  seams  and  fissures  in  the  rocky  formation  of

the  earth's  outer  cni.st,  later  appear  as  hillside  springs  or  seepage  at 
lower  elevations  and  iniieli  of  them  find  their  way  into  the  stream 
channels.  Because  of  many  such  varia])le  influences  dissipating 
preeipitatii)n.  the  i)ortion  of  the  total  finally  reaching  the  stream 
clianncls  may  he  ])i-actically  zero  in  some  regions  of  light  rainfall  or  as 
large  as  nine-tenths  in  areas  wliere  the  rains  are  very  heavy.  A  com- 
parison of  sti-cam  flow  measuivments  with  precipitation  data  reveals 
that  this  fractional  part  of  the  seasonal  precipitation  whicli  finally 
becomes  stream  flow,  varies  principally  with  the  total  amount  falling 
and  that  there  is  a  distinct  relation  between  this  amount  and  the 
quantity  running  off  each  drainage  area,  which  differs  from  that  of 
adjoining  areas  largely  in  the  degree  to  which  mountain  ranges  shelter 
or  expose  them  to  storm  winds  or  to  which  their  elevation  causes 
precipitation  as  snow  or  rain.  This  relation  is  so  predominant  that 
it  suppresses  to  a  great  extent  the  minor  variations  in  this  division  of 
total  seasonal  precipitation  occasioned  by  the  changing  manner  and 
order  of  occurrence  during  each  season  of  storms  and  clear  weather. 

It  so  becomes  possible  to  develop  graphically  this  relation  between 
the  fluctuating  values  of  seasonal  precipitation  and  the  amount  of  run- 
off' from  each  drainage  basin.  A  ready  means  of  expressing  the  fluctuat- 
ing values  of  precipitation  on  each  drainage  basin  is  afforded  by  tlie 
"indices  of  seasonal  wetness"  developed  for  all  parts  of  the  State  in 
Chapter  II,  "Precipitation."  This  presentation  shows  how  the  precipi- 
tation on  California  lands  occurs  mostly  in  storms  that  sweep  over  wide 
areas,  and  the  water-producing  region  of  the  State  is  there  divided  into 
twenty-six  parts,  called  precipitation  divisions,  over  which  these  storms 
sweep  and  precipitate  annually  proportional  amounts  of  rain  or  snow 
throughout  each  division,  which  are  approximately  alike  through  suc- 
ceeding years.  Tlie  series  of  niunbers  named  "indices  of  seasonal  wet- 
ness," ex]n-ess  this  amount  of  rain  or  snow  for  each  of  tlie  twenty-six 
divi.sions  of  tlie  state  in  terms  of  tlie  normal  or  customary  prc^cipitation 
occurring  in  that  division,  and  th(^se  numl)ers  are  tabulated  for  each  of 
the  past  fifty  years.  These  series  of  numbers  then  represent  the 
numerical  relation  between  the  fluctuating  values  of  seasonal  precipita- 
tion during  the  half  century  just  past  and,  in  their  being  a  series  of 
numbers  proportional  to  the  actual  values  falling  in  each  of  tlie  divi- 
sions, are  ecpially  as  useful  as  the  actual  precipitation  records  for 
studying  their  relation  to  the  amount  of  water  runniim'  otT  tlic  drainage 
basins  in  each  season. 

Plates  XVIII  to  LIII,  entitled  "Curves  of  Probable  Kun-off,"  arc 
graphs  of  the  relation  lietween  the  wetness  or  normality  of  the  season's 
precipitation  and  the  amount  of  I'un-off  on  each  of  the  oiu*  hundred 
and  forty  major  di-ainage  basins  or  groups  of  minor  drainage  basins 
in  California.  In  constructing  these  run-otf  curves  the  margins  of 
cross-lined  i)ai)er  were  numhci'ed  beginning  at  the  lower  and  left 
corners.  On  the  upf)er  margin  they  proceed  in  increasing  valnes  trans- 
versely aci'oss  the  sheet  and  re]>resent  the  values  of  the  "index  of 
seasonal  wetness."  They  extend  upward  on  the  side  margin  and 
represent  the  depth  of  seasonal  run-off  in  inches  flowing  off  the  drain- 
age area^  For  each  simultaneous  valne  of  measured  seasonal  run-off 
from  a  drainage  basin  and  ol'  \\\r  "'index  of  seasonal  wetness"  for 
the   preeipitation   division    in    which    the   drainage   basin    is   located,   a

point  -was  plotted  on  one  of  these  cross-ruled  sheets  whieli  is 
at  a  distance  across  the  paper  equal  to  the  value  of  the  "index  of 
seasonal  wetness"  on  the  upper  margin  scale,  and  at  a  distance  upward 
from  the  lower  margin  equal  to  the  value  of  the  seasonal  run-off  on  the 
side  margin  scale.  Points  were  so  plotted  on  these  cross-lined  sheets 
for  ever}^  available  measurement  of  seasonal  stream  flow  in  every  one 
of  the  hundred  and  forty  major  streams  or  groups  of  minor  streams, 
and  smooth  curves  were  drawn  which,  passing  among  the  points, 
average  their  departures  from  exact  positions  upon  the  curves  drawn. 
Numbers  adjacent  to  the  plotted  points  indicate  the  calendar  year 
of  the  last  part  of  the  season  during  which  that  run-off  was  measured. 

These  curves  show  tlie  trend  of  the  relation  between  the  "index  of 
seasonal  wetness"  and  the  run-ofi  from  each  drainage  basin.  They 
pass  through  many  of  the  plotted  points,  but  due  to  the  variable 
weather  in  successive  seasons  which  causes  different  fractions  of  the 
precipitation  to  evaporate  before  running  off  the  collecting  area  into 
the  stream  channels,  some  of  the  points  fall  to  the  side  of  the  mean 
curves.  The  sequence  of  the  storms,  their  intensity,  the  weather  con- 
ditions between  the  occurrence  of  storms,  and  the  character  of  succes- 
sive seasons,  all  influence  this  relation  to  an  indeterminate  degree. 
For  seasons  in  which  these  conditions  favor  a  greater  fractional  part 
of  the  meteoric  waters  evaporating  to  the  atmosphere,  the  points  tend 
to  lie  on  the  lower  side  of  the  mean  curve,  anci  for  seasons  favoring 
a  small  evaporation,  the  points  tend  to  lie  on  the  upper  side.  Succes- 
sive seasons  of  drought  or  heavy  floods  may  also  influence  the  position 
of  the  points,  for  the  quantity  of  ground  water  feeding  the  streams 
does  not  change  inunediately  with  variations  in  the  annual  precipi- 
tation. Instead,  there  is  a  certain  tardiness  in  response  which  places 
these  points  on  either  side  of  the  mean  curve,  according  to  very  recon- 
dite relations  that  obtain  in  the  sequence  of  seasonal  rains  and  snows, 
and  any  one  seasonal  precipitation  may  affect  the  quantity  of  ground 
water  reaching  a  stream  for  a  period  as  long  as  three  years. 

Although  there  are  these  minor  influences  which  tend  to  make  the 
relation  between  the  "index  of  seasonal  wetness"  and  run-oft'  an 
aj)i)roximate  one,  nevertheless  the  data  reveal  that  when  a  reasonable 
numlter  of  measurements  of  seasonal  run-off  are  at  hand,  a  mean  curve 
uuiy  l)e  drawn  which  will  not  change  much  in  position  by  procuring 
aiul  plotting  additional  measurements. 

On  this  series  of  plates.  XVIII  to  LIII,  which  exhibits  the  amounts 
of  run-oft'  entering  all  the  stream  channels  of  the  State  in  seasons 
liaving  different  "indices  of  seasonal  wetness,"  some  streams  have 
many  points  on  their  diagrams  indicating  that  records  of  their  flow 
have  ])een  kept  for  as  many  years;  whereas  others,  on  Avhich  the  records 
ai'c  short,  have  but  few  points,  and  a  large  number  of  the  small  streams 
hav(^  no  points  at  all.  There  are,  however,  sufficient  points  on  the 
diagrams  to  define  curves  for  streams  in  which  seven-eights  of  the 
entire  run-off  of  tlie  mountaijious  area  of  tlie  State  drains  oft'  into  the 
ocean. 

For  the  large  number  of  small  streams  on  which  measurements  have 
never  been  made,  and  for  those  on  which  the  measurements  have  been 
made  for  too  few  years  to  define  a  curve  among  the  small  number  of 
points  on  their  diagrams,  the  run-off  curves  were  developed  throufrh

comparison  of  the  characteristics  of  their  drainage  areas  with  the 
characteristics  of  the  areas  for  which  there  are  ample  records  to  con- 
strnct  curves.  The  effect  of  the  magnitude  of  mean  seasonal  precipi- 
tation, of  the  nsnal  storm  intensities,  of  the  elevation  of  watershed, 
and  of  the  absorbency  of  its  surface,  upon  the  shape  and  position  of 
these  rnn-otf  curves  was  investigated,  and  the  comparison  of  these 
characteristics  of  each  drainage  area  provided  the  means  for  locating 
estimated  run-otf  curves  on  the  diagrams  for  areas  from  which  the 
run-off  had  either  not  been  measured  at  all,  or  had  been  measured  only 
for  a  year  or  two. 

These  curves  for  drainage  basins  in  all  parts  of  the  State  are 
generally  similar  to  each  other  in  shape  and  somewhat  similar  in 
position  on  the  diagrams.  Because  of  the  unit  of  value  selected  to 
represent  rainfall,  the  index  of  seasonal  wetness,  and  to  represent  run- 
off, the  inches  in  depth  over  the  land;  these  diagrams  as  drafted 
are  comparable  one  with  the  other  and  may  be  superimposed  to  study 
the  effect  of  the  characteristics  of  their  several  drainage  areas  upon 
the  shape  and  position  of  their  curves.  For  purpose  of  comparing  this 
effect  of  their  characteristics,  several  plates  were  prepared  which 
assemble  the  curves  superimposed  on  each  other  in  different  group- 
ings. Plate  LIV,  "Comparison  of  Run-off  Curves  CTrouped  Ceographi- 
cally, "  (run-off  plotted  to  inches  depth  on  drainage  basin),  makes  an 
assembly,  placing  on  one  diagram  those  curves  whose  drainage  basins 
lie  in  adjacent  localities.  Plate  LV,  "Comparison  of  Run-off  Curves 
Grouped  by  Types,"  (run-oft'  plotted  to  inches  in  dopth  on  drainage 
basin),  makes  a  second  comparison  of  the  run-off  curves  assembling 
on  one  diagram  those  curves  which  are  most  alike  in  shape  and  position. 
Com[)arisons  are  again  made  of  these  curves,  first  by  locality  groups 
and  second  by  similarity  of  shape  and  position,  on  Plates  LVI  and 
LVII,  but  on  these  plates  the  unit  of  value  representing  the  run-oft' 
from  the  drainage  basins  was  changed  from  inches  in  depth,  used  on 
the  two  other  comparison  plates  and  on  all  the  run-off  curves,  to  per 
cent  of  the  mean  seasonal  run-off.  By  making  this  change  in  the  unit 
to  M'hich  the  data  are  plotted,  the  resulting  curves  have  an  altered 
relation  one  with  another  which  aft'ords  added  means  of  studying  the 
effect  of  the  characteristics  of  their  drainage  areas  in  changing  their 
shape  and  position  relative  to  one  another  on  the  diagrams. 

It  was  by  making  the  comparisons  afforded  by  these  four  plates  that 
the  run-off  curves  were  developed  for  every  drainage  basin  in  the 
State  of  California.  Those  curves  constructed  directly  from  measure- 
ments of  run -off  are  for  streams  which  have  an  aggregate  drainage 
area  of  two-thirds  of  the  entire  mountainous  area  of  the  state  and 
which  have  an  aggregate  run-off  of  seven-eights  of  the  total  from  the 
state's  water-producing  area.  The  curves  dev(^lopcd  by  comparison 
are  greater  in  number  fhan  those. constructed  directly  from  measure- 
ments, but  their  drainage  areas  are  the  smaller  ones  and  have  the 
lesser  run-oft".  The  curves  developed  by  comparison  were  all  obtained 
by  following  a  uniform  procedure  and  identical  scientific  principles, 
and  they  are  based  not  only  on  all  the  information  available  concern- 
ing their  own  drainage  areas,  but  also  upon  the  knowledge  gained  from 
the  gagings  of  rtni-olf  on  all  the  measured  streams  of  the  State.

These  curves  indicate  the  depth  of  run-off  from  their  respective 
drainage  areas  which  may  occur  in  a  season  having  a  precipitation  bear- 
ing a  relation  to  the  mean,  indicated  by  the  "Index  of  Seasonal 
Wetness."  By  the  use  of  the  "Indices  of  Seasonal  Wetness"  derived 
for  all  divisions  of  the  state  and  presented  in  Chapter  II,  the  amount  of 
run-oft'  in  every  stream  was  obtained  from  these  curves  for  each  year 
that  the  flow  was  not  measured,  of  the  fifty  for  which  indices  were 
developed.  In  Tables  34  to  173,  "Seasonal  Run-off  Data,"  the  values 
of  seasonal  run-oft'  for  every  drainage  area  in  the  State  are  tabulated 
for  the  full  fifty-year  period.  The  "Indices  of  Seasonal  Wetness" 
for  the  precipitation  division  in  which  each  stream  is  located,  are  also 
tabulated  there.  In  addition,  in  the  column  to  the  right,  are  printed 
the  values  of  seasonal  run-off  measured  at  the  stream-gaging  stations 
and  the  average  fraction  of  this  expresesd  in  per  cent,  that  occurs  in 
each  of  the  twelve  months  of  the  year.  Footnotes  to  the  tables  show 
in  v.-liat  way  the  measured  quantities  were  altered  to  obtain  the  total 
run-off  above  the  main  body  of  agricultural  land  on  the  stream,  for 
in  many  instances  the  entire  drainage  area  is  not  tributary  to  the 
stream  at  the  gaging  station  and  in  others  water  has  been  diverted  at 
points  upstream.  For  all  seasons  in  which  no  measurements  were  made, 
the  run-off  was  obtained  by  entry  on  the  run-off  curve  with  the  index 
of  seasonal  wetness  for  that  season. 

In  these  tables,  140  in  number  and  one  to  a  stream  or  group  of 
small  streams,  is  assembled  the  seasonal  flow,  either  measured  or 
determined  by  comparison,  for  fifty  years  and  for  the  entire  water- 
producing  area  of  the  State.  The  mean  value  for  this  fifty-year  period 
is  presented  as  the  mean  seasonal  flow  of  the  stream,  since  so  far  as 
is  known  the  inclusion  of  additional  records  would  not  materially 
alter  this  average.  The  only  direct  information  on  this  is  the  rain- 
fall records  at  Sacramento,  San  Francisco  and  San  Diego.  At  these 
]ioints  only,  have  precipitation  records  been  kept  much  longer  than 
fifty  years  and  these  are  for  over  seventy  years.  The  average  value  for 
fifty  years  in  Sacramento  is  one  per  cent  greater  than  that  for  seventy- 
three  years,  in  San  Francisco  it  is  two  per  cent  greater,  and  in  San 
Diego  it  is  three  per  cent  less. 

Table  2,  "^Mean  Seasonal  Run-oft'  in  California  Streams."  which 
follows  herewith,  presents  the  values  of  mean  seasonal  flow  summarized 
from  tables  34  to  173,  and  gives  for  each  stream  or  group  of  streams 
the  reference  to  the  table  number  in  which  the  detail  information  is 
tabulated,  and  the  plate  number  of  the  run-off  curve  used  in  develop- 
ing the  tabular  detail  is  given  in  the  tables  of  seasonal  run-off  data. 
These  values  of  mean  seasonal  run-off  average  the  widely  fluctuating 
values  of  successive  years  and  represent  the  average  quantity  to  be 
expected  year  in  and  year  out,  including  the  large  floods  of  unusual 
occurrence  as  well  as  the  floods  of  lesser  magnitude  which  occur  fre- 
quently, and  also  the  diminutive  flow  of  the  seasons  of  drought.  This 
is  a  comprehensive  statement  of  the  volumes  of  water  in  all  the  rivers 
and  .streams  of  the  state  without  exception.  The  geographic  location 
of  their  drninage  basins  is  shown  on  Plate  XY,  "Map  Showing 
Tiouiularics  of  Draiiuuj'e  Ba,sins. "

60  WATER   RESOURCES    OF    CALIFORNIA, 


CHAPTER  V. 


FLOOD  FLOW  IN  STREAMS 

Coincident  with  the  progress  of  civilization,  growth  of  industry,  and 
extension  of  agriculture  that  accompanies  increase  in  population,  man 
and  his  improvements  encroach  upon  new  lands  hitherto  unoccupied. 
On  areas  of  recent  encroachment,  attracted  there  by  the  superior  fer- 
tility of  the  farming  lands,  man  is  now  waging  a  contest  with  the  waters 
of  nature  for  occupancy  of  hundreds  of  thousands  of  acres  of  river- 
bottom  soil.  The  contlict,  more  hazardous  in  not  being  continuous, 
rages  at  irregular  intervals  of  time,  and  often  several  entire  seasons 
pass  with  man  and  his  works  left  in  peaceable  possession  of  these  areas, 
undisturbed  by  rising  floods.  But  always,  though  at  intervals,  huge 
volumes  of  water  are  poured  into  the  stream-channels  from  climaxes 
of  precipitation,  both  prolonged  and  severe,  and  these  waters,  too  great 
to  be  confined  between  the  low  banks  of  the  river-bottom  lands,  renew 
the  strife  Avith  man  for  occupancy  by  threatened  inundation  of  these 
areas.  In  the  contest  for  occupancy  of  these  regions,  man  has  con- 
structed many  miles  of  earth  dykes  to  stem  the  overflowing  waters; 
river  channels  have  been  enlarged,  their  crooked  courses  straightened, 
relief  channels  excavated,  and  divers  works  built  to  combat  the  attack- 
ing waters  and  prevent  them  from  spreading  out  over  the  river-bottom 
lands  in  the  way  of  the  past.  In  the  more  advanced  communities, 
these  works  protect  well-kept  orchards  and  acres  of  high-priced  vege- 
table crops  whose  wealth-producing  powers,  abetted  by  the  unu.sual 
fertility  of  the  soils,  have  created  many  beautiful  homes,  villages,  and 
towns  with  substantial  public  improvements ;  and  well-paved  highways 
interconnect  all.  Secure  in  having  successfully  Avithstood  many  at- 
tacks, these  regions  are  nevertheless  imperiled  at  times  by  the  rise  of 
waters  to  heights  but  rarely  experienced,  for  the  occurrence  of  floods, 
their  size  and  duration,  are  the  resultant  of  varying  sequential  combin- 
ations of  weather  occurrences  which  produce  at  their  climax,  precipi- 
tation of  unusual  intensity  or  of  continuance  for  protracted  periods  of 
time.  That  these  flood-producing  precipitations  nuiy  occur,  the  atmos- 
phere must  be  lowered  in  temperature  so  much  that  it  becomes  greatly 
oversaturated  with  water-vapor  and  precipitates  the  excess  earthward 
as  rain.  Unless  this  temperature  is  markedly  reduced  below  that  at 
which  the  atmosphere  is  saturated,  the  resulting  showers  are  light  and 
of  short  duration.  INIarked  reductions  in  atmospheric  temperature 
take  place  only  when  the  warm  aii*  fr<mi  the  ocean  is  transported  over 
the  cool  land"  by  winter  winds,  and  for  strong  thermal  contrasts  to 
occur,  air  off"  tlie  ocean  is  usually  transported  many  miles.  To  have 
these  winds  blow  over  vast  areas  and  follow  previous  occurrences  of 
sunshine  and  clouds  in  proper  order  to  induce  strong  temperature 
contrasts  requires  such  a  cooi-dinated  sequence  of  these  many  meteoro- 
lotrical  phenomena,  that  it  seldom  happens.  For  every  increased  degree 
of~  thermal   contrast   produced    coincident   to   widespread    wind    move-

ments  from  off  the  ocean,  a  more  extraordinary  coordination  of  the 
weather  must  occur  over  a  large  territory  for  months  preeedini^. 

So  to  create  storms  of  flood-producing  magnitude,  the  sequence  of 
atmospheric  disturbances  over  many  localities  must  have  coincidence 
for  considerable  periods  of  time.  With  the  extension  of  the  locality 
wet  by  storms,  and  their  increasing  intensity,  a  more  complete  coordi- 
nation of  weather  is  required  over  greater  areas  for  a  longer  time,  and  so 
the  less  likely  is  it  to  occur.  Also,  the  rain-producing  tendencies  in 
the  atmosphere  during  the  storms  must  predominate  over  the  influences 
tending  toward  their  dispersal  or  toward  abation  of  their  violence,  in 
order  that  the  storms  may  be  exceedingly  great  in  intensity  or  of  long 
duration,  and  these  are  least  apt  to  occur  in  the  most  complete  predomi- 
nance. Therefore  the  chance  that  meteoric  events  oecuring  over  large 
areas  will  unite  in  harmonious  combination  to  produce  great  storms, 
becomes  smaller  and  smaller  as  the  storms  become  greater.  So  it  is  that 
the  storms  of  great  magnitude  visit  a  drainage  area  at  but  infrequent 
intervals,  and  so  it  is  that  precipitations,  in  visiting  the  drainage  basins 
in  all  variatioujs  from  the  almost  insignificant  summer  showers  that 
barely  dampen  a  few  acres  of  ground  before  again  becoming  vapor  of 
the  air,  to  the  driving,  widespread  storms  that  continue  in  fluctuating 
intensity  through  a  fortnight  or  more  and  drench  thousands  of  square 
miles  of  the  mountain  area,  are  separated  in  time  by  intervals  increas- 
ingly long  on  the  average  as  the  storms  become  greater  in  magnitude. 
For  these  reasons,  the  waters  of  flood-creating  storms  pass  down  the 
stream  channels  less  frequently  as  their  volumes  increase,  for  generally 
the  magnitude  of  floods  corresponds  to  the  magnitude  of  the  storms 
creating  them. 

However,  to  further  complicate  the  occurrence  of  conditions  that 
increase  the  volume  of  flood  waters,  the  portion  of  the  precipitation 
shed  to  the  stream  channels  is  not  alike  for  all  storms.  The  absorbency 
of  the  surface-covering  of  the  drainage  area  at  the  time  when  the  storm 
waters  are  precipitated  upon  it,  is  most  important  in  determining  the 
apportionment.  Often  heavy  storms  have  such  a  large  fraction  of 
their  waters  used  in  wetting  the  catchment  area,  that  they  do  not  con- 
tribute excessively  to  stream  flow.  It  is  only  when  a  sodden  soil,  wet 
to  saturation  from  previous  downpours,  or  when  the  earth's  crust  is 
frozen,  that  all  of  the  rainfall  reaching  the  earth's  surface  runs  off  to 
the  waterways.  If,  falling  instead,  on  a  dry  soil  or  on  a  surface  that 
is  absorbent  because  of  an  open  and  i)orous  structure  and  whose  inter- 
stices are  not  already  filled  with  rain  or  snow-water,  large  portions  and 
sometimes  all  of  the  precipitation  are  taken  up  by  the  earth's  covering 
and  little  or  none  reaches  the  stream  channel  to  produce  floods.  But 
with  long-continued  storms,  even  the  more  porous  coverings  may  be- 
come moisture-saturated  before  their  cessation  and  shed  great  quantities 
of  water  to  the  drainage  channels  during  the  latter  part  of  the  down- 
pour. In  other  instances,  when  warm  rains  fall  on  snow-covered 
regions,  the  rain-water  may  be  joined  by  melting  snow  to  further  swell 
the  rising  streams  and  a  volume  of  water  may  i)ass  down  the  channels 
greater  than  the  entire  rainfall.  These  conditions  of  the  earth's  sur- 
face-covering at  the  time  of  the  storm,  favorable  or  unfavorable  to  shed 
the  meteoric  waters  cast  upon  it,  are  largely  resultant  from  the  previous 
weather  happenings  in  the  locality ;  so  that  to  produce  large  floods, 


62  WATER    RE^^OL'RCES    OF    CALIFORXIA. 

the  precedinor  weather  occurrences  must  not  only  coordinate  to  make 
heavy  downpours,  ])ut  must  also  coordinate  to  render  the  earth's  sur- 
face on  the  collectiuiT  area  capal)le  of  quickly  turning  off  nearly  all  the 
water  it  receives.  The  simultaneous  culmination  of  weather  conditions 
on  the  draina<re  area  favoral)le  to  large  and  rapid  run-off.  may  l)e 
readied  in  all  conceivalile  de^rrees  of  value  and  so  result  in  floods  vary- 
infj  in  severity  and  frequency  of  occurrence  between  equally  wide  limits. 

That  the  long  series  of  meteorological  storm-inciting  events  should 
so  transpire  that  their  climax  may  precipitate  waters  on  a  drainage 
basin  at  the  time  its  surface  is  in  favoralile  condition  to  shed  nearly 
all  the  precipitation  falling  upon  it,  is  an  expectancy  of  still  more 
remote  occurrence  than  that  the  flood-producing  storm  should  occur. 
The  likelihood  of  precipitation  falling  on  and  running  off  a  drainage 
area  in  flood  volumes  is  therefore  unusual  and  the  greater  the  magni- 
tude of  the  flood,  the  less  usual  may  be  its  occurrence.  This  frequency 
with  which  floods  of  the  varying  magnitudes  may  be  expected,  is  there- 
fore of  prime  interest  to  man  who  wages  contest  with  nature  for  occu- 
pancy of  the  river-bottom  lands. 

To  view  the  frequency  of  occurrence  of  floods  in  their  various 
volumes  and  to  draw  deductions  therefrom,  special  diagrams  were  pre- 
pared to  display  all  the  flood-measurements  from  the  records  of  the 
T'nited  States  Geological  Survey.  These  diagrams  are  Plates  LVIII 
to  XCIII,  ''Probable  Frequency  of  Flood  Discharge,"  and  there  is  one 
for  each  of  the  one  hundred  and  forty  streams  or  groups  of  minor 
streams  in  the  state.  Points  are  plotted  on  these  diagrams  in  such  a 
manner  that  their  position  indicates  the  frequency  during  the  period 
of  stream  measurement  with  which  floods  passed  down  the  channels, 
in  volumes  exceeding  certain  magnitudes.  The  scale  on  the  side  or 
longer  margin,  numbered  consecutively  from  0.4  to  800,  expresses  this 
frequency  as  the  average  number  of  occurrences  during  one  hundred 
years.  While  niunber  1.0  stands  for  an  average  occurrence  of  once  a 
century,  the  extreme  number  of  0.4  represents  an  occurrence  once  in 
two  hundred  and  flfty  years,  and  the  extreme  of  800  represents  an 
occurrence  of  eight  hundred  times  a  century,  the  equivalent  of  eight 
times  in  one  year.  The  top  or  shorter  margin  scale  of  these  diagrams 
has  divisions  expressing  the  magnitude  of  flood  flows  in  terms  of  inches 
of  depth  to  which  the  volume  of  water  running  off  in  twenty-four  hours 
would  submerge  the  drainage  area  if  spread  evenly  over  its  surface. 
The  scale  divisions  are  numbered  consecutively  from  0.1  inch  to  10.0 
inches  in  depth.  These  values  may  be  converted  to  the  more  usual 
terms  of  cubic  feet  ])er  second  tlu'outrb  their  multijilication  by  the  con- 
version factor  that  is  on  tlie  diaiiram.s  imnuHliately  adjacent  to  the  top 
margin  scale.  The  less  usual  \uiit  of  inches  in  depth  on  the  drainage 
area  running  off  in  twenty-four  hours  was  employed  to  express  the 
volume  of  flood  flows,  however,  so  that  all  the  one  hundred  and  forty 
streams  in  the  state  would  have  diagrams  with  .scale  divisions  which 
are  equal  in  valne  and  numbered  alike.  This  makes  all  the  diagi'ams 
comparal)le,  one  with  another. 

The  cross-ruled  lines  on  tliese  digrams  have  not  iho  (Mjual  s}>acing 
customarily  used  foi-  technical  exposition,  but  instead,  are  separated 
by  intervals  growing  ])rogressively  smalh-r  for  each  successive  unit  of

smallor  is  uiiifonn  on  al!  diagraiiis  and  is  known  uiathenialieally  as 
the  "loo'arithmic  scale."  The  artifice  of  usino-  this  special  scale  is  oi' 
great  valne  in  drawing  the  curved  lines  on  the  diagrams  in  a  mean  posi- 
tion to  the  plotted  points  and  in  extending  the  extremities  of  the  curves 
to  the  parts  of  the  sheets  where  no  points  are  found. 

Each  point  plotted  on  the  diagrams  stands  for  all  the  flood  flows 
which  crested  at  volumes  greater  than'that  shown  by  the  top  margin 
scale,  and  which  occurred  a  numljer  of  times  during  the  peiiod  of 
measurement  equivalent  to  the  number  of  times  in  one  hundred  years 
indicated  on  the  «ide  margin  scale.  These  points  cluster  on  the  lower 
part  of  the  diagrams  since  the  records  disclose  only  the  floods  which 
occurred  once  or  more  during  the  period  of  measurement,  and  the  long- 
est record  is  twenty-eight  years.  The  point  nearest  the  top  on  any  of 
the  diagrams  therefore  lies  close  to  the  line  numbered  4.0  which  is  an 
expectancy  of  four  times  within  one  hundred  years  or  once  in  twenty- 
flve  years.  Flood  occurrences  that  may  not  be  expected  as  often  as 
this,  are  indicated  by  the  parts  of  the  smooth  curves  extending  beyond 
the  positions  of  the  uppermost  points.  It  w^as  to  enable  the  accurate 
extension  of  these  curves  through  the  mean  positions  of  the  points,  to 
parts  of  the  diagrams  depicting  frequencies  of  once  in  one  hundred  to 
once  in  two  hundred  and  fifty  years,  that  the  " logaritlimic  scale"  was 
adopted  in  spacing  the  cross-ruled  lines.  It  may  be  observed  that  the 
employment  of  this  scale  causes  all  the  curves  to  take  the  conformation 
of  a  parabola,  and  that  the  portion  of  sharper  curvature  is  well  defined 
by  points  representing  measurements  on  the  diagrams  of  measured 
streams,  while  the  extended  portion  of  the  curves  is  gentle  in  its  change 
of  direction  and  approaches  a  straight  line.  Therefore  the  extension 
of  the  curves  to  the  parts  of  the  diagrams  without  points  was  accom- 
plished with  precision. 

Because  of  the  great  similarity  in  shape  of  the  curves  when  plotted 
on  logarithmic  scales,  and  their  comparability  resulting  from  the  ex- 
pression of  the  volume  of  flood  flows  in  terms  of  inches  in  depth  on 
the  drainage  area,  curves  could  be  developed  for  streams  which  have 
not  l)een  measured.  Such  curves  were  developed  through  comparison 
of  the  physical  and  precipitation  characteristics  of  the  drainage  areas 
throughout  the  state.  To  reveal  the  eifect  of  these  physical  character- 
istics and  the  usual  storm  features  of  the  drainage  areas,  upon  the 
shape  of  the  curve  and  its  position  on  the  diagram,  Plate  XCIV,  was 
]u-epared.  This  plate,  "Comparison  of  Curves  of  Probable  Frequency 
of  Floor  Discharge,"  compares  on  one  sheet,  the  curves  of  all  the 
streams.  By  means  of  these  comparisons,  curves  were  developed  for 
the  many  smaller  streams  of  California  on  which  no  measurements  have 
been  made.  The  curves  prepared  fi'om  measurements  as  well  as  all  the 
ijiterpolated  curves,  are  shown  on  this  comparison  plate. 

All  of  these  curves  sweep  upwardly  from  the  lower  left  hand  corners 
of  the  diagrams,  first  bearing  to  the  right  but  rapidly  swerving  towards 
the  tops  of  the  sheets.  Although  they  approach  positions  parallel 
with  the  up-and-down  margin,  none  of  them  become  vertical  even  at 
theii-  upper  extremities.  Should  the.y  have  arrived  at  vertical  direc- 
tions, the  values  of  the  flood  volumes  intersected  by  them  on 
the  upper  margin  scales  would  represent  the  maximum  floods  which 
might   ever  occur  i-egardless  of  their   iiifi'e(|ueiu'y.     As  the  cui'vcs  ap- 


64  WATER  RESOURCES   OF   CALIFORNIA. 

proach  the  vei'tic-al,  their  further  extensions  become  so  nearly  the  direc- 
tion of  the  side  margin  seales  which  are  marked  off  to  indicate 
frecjuency  of  tloods,  that  their  values  on  the  top  margin  scales  do  not 
alter- much  as  the  curves  advance  on  the  frequency  scales;  so  that  the 
more  nearly  vertical  these  curves  become,  the  less  do  the  infrequent 
floods  exceed  the  more  usual  ones  in  magnitude.  The  broad  swing  to 
the  right  at  tlie  lower  end  of  these  curves,  in  having  direction  well  apart 
from  the  vertical,  show  that  the  smaller  floods  mount  rapidly  in  size 
for  slightly  lengthening  average  lapses  of  time  between  them. 

The  continued  slight  inclination  to  the  right  of  all  these  curves  at 
their  extreme  upper  ends  and  their  failure  ever  to  become  straight  up 
and  down,  reveals  that  the  maximum  flood  flow  has  not  occurred  in  any 
stream  of  the  state  since  white  man  has  resided  here,  and  that  the 
greatest  flood  yet  observed  in  any  of  the  streams  may  be  exceeded  at 
any  time,  but  only  at  average  intervals  that  are  increasingly  long  as 
the  magnitude  of  the  flood  is  greater.  The  diagram  representing  the 
flood  flows  on  Sacramento  River  at  Ked  Bluff  shows  that  the  expectancy 
of  a  flood  flow  having  a  volume  exceeding  250,000  cubic  feet  per  second, 
is  four  times  in  a  century;  of  one  exceeding  800,000  cubic  feet  per  sec- 
ond, is  once  in  a  century;  and  a  flood  exceeding  330,000  cubic  feet  per 
second  has  an  expected  occurrence  of  but  once  in  two  hundred  years; 
and  that  still  larger  volumes  may  flow  down  the  channel  at  average 
intervals  greater  than  this.  In  general,  the  diagrams  show  that  floods 
will  oc(;ur  once  in  ftmr  years  in  more  than  tlouble  the  size  that  is  not 
exceeded  on  an  average  more  often  tlian  once  a  year;  more  tluni 
treble  this  volume  once  in  twenty  years;  exceeding  quadruple  this 
volume  once  in  two  hundred  years;  and  at  intervals  of  a  few  thou- 
sand years  a  flood  may  be  expected  in  at  least  quintriple  the  volume 
which  is  exceeded  not  oftener  on  the  average  than  once  yearly,  for  even 
at  times  of  occurrence  that  are  as  infrequent  as  once  in  two  centuries, 
the  curves  depicting  these  natural  laws,  in  still  progressing  on  the 
diagrams  farther  and  farther  into  the  region  of  greater  floods,  indicate 
that  most  extraordinary  floods  may  occur  at  average  intervals  of  once  in 
many  thousands  of  years. 

Table  175,  "Flood  Flow  in  California  Streams,''  tabulates  tlie 
greatest  flood  flows  which  have  been  measured,  giving  the  name  of  the 
stream,  date  of  measurement,  and  allied  information.  The  table  also

CHAPTER  VI. 


EQUALIZATION  OF  THE  PERIODIC  RUN-OFF  FROM  THE 

MOUNTAINS. 

Three-fourths  of  California's  waters  run  off  their  mountainous 
catchment  areas  to  concentrate  in  the  stream  channels,  hurry  down  their 
courses,  and  pass  by  the  low-lying  agricultural  lands  within  forty-five 
days  after  their  precipitation  from  the  atmosphere.  Following  the  spo- 
radic precipitation  so  closely,  run-off  is  also  irregular  in  its  occurrence 
but  much  \eiH  so.  The  lapse  of  time  between  precipitation  and  almost 
complete  run-off,  although  not  long,  is  still  sufficient  to  merge  the  stream 
flow  derived  from  successive  storms  and  run-off  nasses  wave-like  down 
the  stream  channels,  and  is  fairly  continuous  through  the  winter 
months.  However,  the  long  dry  summers  without  rain  to  replete  the 
supply,  cause  interruptions  in  the  flow  at  regular  yearly  intervals  so 
that  run-off  is  periodic  in  its  occurrence.  Still,  much  of  the  precipita- 
tion on  tlie  collecting  areas  does  not  join  the  .stream  flow  quickh^,  but  is 
withheld  by  wetting  the  earth 's  crust  and  covering,  and  were  it  not  that 
the  ever-acting  process  of  evaporation  so  reduces  the  volume  of  retarded 
waters,  their  quantities  would  be  sufficient  "to  largely  equalize  the  perio- 
dicity of  flow.  Instead,  only  minor  parts  of  these  retained  waters  ever 
reach  the  stream  channels  and  these  are  so  small  in  cpiantity  that  they 
do  not  nearly  equalize  the  floods  that  quickly  follow  precipitation. 

Of  the  storm  waters  that  do  not  immediately  collect  in  the  ravines 
and  gullies  to  start  on  their  oceanward  journey,  some  wet  the  earth's 
surface  or  sink  into  its  porous  structure,  some  are  absorbed  by  the 
cover  of  vegetation  finding  support  in  the  shattered  rocks  and  top-soil, 
while  others  remain  frozen  in  snow  fields,  drifts,  or  banks  until  release 
comes  with  warmer  weat^*^r.  and  they  all  have  continuous  contact  with 
the  atmosphere  except  those  that  percolate  to  depths  belows  the  earth's 
surface.  This  contact  with  the  atmosphere  is  uninterrupted  during  the 
entire  period  of  the  water's  detention  on  its  catchment  area.  It  occurs 
over  surfaces  vastly  greater  in  area  than  that  of  the  earth  upon  which 
the  waters  were  precipitated ;  for  the  atmosphere,  in  adapting  its  shape 
with  facile  consonance  to  minute  irregularities  of  contacting  solids,  not 
only  envelops  every  protruding  rock  or  clod,  mound  of  soil  or  snow, 
and  every  branch,  stem  or  leaf  of  the  grass  and  trees,  but  even  pene- 
trates the  pores  separating  the  structural  particles  of  the  snow,  soil, 
and  rocks,  to  still  further  enlarge  the  contacting  areas.  All  these  sur- 
faces when  wet  by  rain  or  snow,  contact  liquid  or  solid  water  with  the 
air.  and  evapoi-ation  takes  place  unless  the  air  be  already  saturated 
with  water  vapor.  Tlie  saturation  in  the  zones  of  contact  for  any  but 
limited  periods  of  time,  is  prevented  however,  by  the  continually  mov- 
ing zephyrs  and  breezes  which  mix  the  atmosphere  aliout  and,  should 
any  of  these  surfaces  become  dry,  the  moisture  within  the  pores  of  the 
soils  or  rocks,  mid  grass  or  trees,  is  drawn  to  the  surface  by  their  capil- 
lary powers  and  rcmoistens  the  solid  surfaces  in  contact  with  tlie  air.

Ill  this  way  iiiuisture  may  be  lirouglit  back  to  the  surface  to  be  evapo- 
rated, oven  after  penetrating-  several  feet  into  tlie  earth's  crust.  So 
evaporation  is  persistently  in  proyre.ss  and,  effectively  and  without 
respite,  is  reducing  the  volume  of  waters  delayed  in  runnins;  off  the 
catehment  area,  and  from  one-fourth  to  three-fourths  of  all  the  waters 
that  fall  from  the  atmosphere  are  evaporated. 

Evaporation  is  so  active  everywhere  and  at  all  times,  that  even  the 
percolating  waters,  which  penetrate  below  the  earth's  surface  too  far 
for  the  capillary  powers  of  its  covering  to  draw  them  back  and  which 
are  the  only  delayed  waters  not  subject  unceasingly  to  evaporation, 
are  finally  exposed  to  the  air  at  the  springs,  meadows,  and  marshes 
wliere  they  again  make  their  appearance,  and  give  up  moisture  to  the 
atmos])]iere.  Therefore,  although  the  waters  that  are  delayed  more 
than  forty-five  days  from  completing  their  journey  to  the  ocean's  shore, 
are  often  large  portions  of  the  total  precipitation  on  the  drainage  basins, 
they  are  so  immensely  depleted  in  volume  before  reaching  the  stream 
channels,  that  tho.^e  finally  becoming  run-off  constitute  only  one-fourth 
of  the  state's  waters. 

The  storms  that  precipitate  these  waters  on  California's  mountains 
in  billions  of  tons  annually,  especially  the  large  ones  in  Avhich  the 
greatest  volumes  of  water  are  ejected  from  the  atmosphere,  extend 
over  regions  of  thousands  of  square  miles  and  give  up  proportional 
amounts  of  their  vaporous  burden  to  the  localities  traversed.  Data 
are  presented  in  Chapter  IT,  "Precipitation,"  to  show  how  these 
storms  sweep  over  great  areas  including  both  mountains  and  valleys 
alike,  and  Plate  I,  "Comparison  of  Seasonal  Index  of  Wetness  in  Moun- 
tain and  Valley  Areas,"  shows  how  proportional  amounts  of  storm 
waters  fall  both  upon  the  low-lying  agricultural  lands  of  the  Sacra- 
mento Valley  and  u])on  the  mountains  thousands  of  feet  higher  and  dis- 
tant many  miles  to  the  east.  So  the  bulk  of  the  run-oft'  from  the 
mountain  area,  in  occurring  within  forty-five  days  after  the  storms  orig- 
inating it,  passes  down  the  waterways  at  a  time  when  the  state's  agricul- 
tural lands  are  already  replete  with  moisture,  for  the  same  wide-spread 
storms  that  drench  the  mountains  precipitate  some  of  their  waters  upon 
the  lower  flat-lands.  Therefore  the  state's  waters  in  the  natural  regi- 
men of  the  streams,  are  largely  unavailalile  for  u.se  on  the  agricultural 
lands,  which  need  them,  but  not  witliin  foi-fy-five  days  after  the  winter 
rains. 

To  detain  these  waters  on  their  catcliiiiciit  ai'ca  until  the  sumiuer 
drouth  arrives  and  then  release  them  to  augment  the  waning  stream 
flow,  requires  that  reservoirs  be  provided  to  temporarily  store  them. 
With  space  provided  to  capture  the  storm  waters  which  would  other- 
wise immediately  hurry  down  the  stream  channels,  the  rapid  rush  of 
the  state's  waters  back  to  the  ocean  may  be  arrested.  The  winter  floods 
may  thus  be  reduced  and  their  useless  volumes  of  water  subjected  to 
man's  direction  in  flowing  down  the  watei-  courses.  In  this  way  they 
may  be  u.scd  to  wet  the  di'y  agricullural  lands  during  the  long  Cali- 
fornia summers,  or  for  industrial  and  (lomcstic  |>urposes  that  recjuire 
water  during  the  months  of  the  year  in  which  the  stream  flow  is 
naturally   small. 

Artificial  storage  cai)acity  may  thus  be  made  to  e(|uali/.i'  the  erratic 
flow  in  the  state's  water  courses  for  the  convenience  of  man's  industrial 
cnteri)rises,  although  nature,  in  retaining  large  ]>ortions  of  \\\o  preeipi-

tatioii  ou  the  eatcliment  area,  does  not  substantial!}'  alter  the  perio- 
dicity of  flow ;  and  should  storage  be  provided  in  adequate  amounts,  the 
entire  annual  water-i>roduetion  could  be  made  to  How  at  tinu^s  useful 
to  man  if  it  were  not  that  some  of  the  waters  artificially  retarded,  return 
to  the  atmosphere  even  as  those  detained  by  nature  do.  However,  by 
providing  storage  space  in  concentrated  volumes  and  witli  small  water- 
surface  exposure,  man  may  limit  the  part  evaporated  to  less  than  ten 
per  cent.  This  is  very  much  smaller  than  the  evaporation  losses  from 
the  vastly  greater  surfaces  of  nature's  delayed  waters;  Init  if  floods 
are  held  in  storage  on  the  collecting  areas  for  more  than  one  season 
amounts  larger  than  ten  per  cent  may  diffuse  into  the  earth's  gaseous 
envelope,  although  even  then  they  are  never  as  large  as  from  the  waters 
detained  by  nature. 

With  the  run-off  of  very  wet  years  as  much  as  four  times  that  of 
dry  ones  and  the  succeeding  seasons  attaining  all  manner  of  inter- 
mediate values,  the  excess  waters  of  very  copious  winters  must  often 
be  carried  over  several  years  to  supplement  the  flow  of  deficient  seasons 
in  order  to  completely  equalize  the  periodic  run-off.  Since  the  per- 
centage evaporated  becomes  larger  and  larger  with  the  lengthening 
time  of  detention,  the  fraction  of  the  total  waters  of  a  drainage  basin 
wliich  may  be  made  subservient  to  man.  becomes  smaller  and  smaller  as 
tlie  stream-flow  is  more  erratic  in  occurrence.  In  very  erratic  streams 
therefore,  even  when  unlimited  storage  space  is  provided,  not  more  than 
fifty  per  cent  of  its  total  waters  may  be  made  to  sul)serve  man,  while 
in  streams  of  uniform  discharge  as  much  as  ninety  per  cent  may  be 
utilized. 

The  degree  to  which  the  waters  in  all  the  streams  of  the  state  appear 
in  erratic  volumes,  has  been  analyzed  and  the  amounts  made  available 
to  man  by  filling  various  volumes  of  storage  capacity  with  flood  waters 
for  deferred  use.  have  been  determined.  To  do  this,  fifty-four  plates 
were  prepared.  Plates  XCV  to  CXLYllI,  "]\Iass  Diagrams  of  Run-off." 

The  monthly  flow  in  every  stream  or  group  of  streams  is  delineated 
on  these  plates  for  the  past  fifty  years  and  in  such  a  manner  that  the 
sequence  of  their  fluctuating  volumes  is  pictured  by  the  inclinations 
and  curvatures  of  lines  drawn  across  the  diagrams  from  left  to  right. 
These  sinuous  lines  in  tlieir  cross-wise  progress,  incline  upward  during 
periods  of  run-off  greater  than  normal  and  turn  downward  during 
times  that  are  below  normal  run-oft';  the  steepness  of  their  slopes  in 
either  case  indicates  the  extent  of  departure  from  the  average  rate  for 
a  mean  season.  Sections  that  parallel  the  heavy-drawn  zero  lines  and 
incline  neither  up  nor  down,  are  periods  which  have  exactly  the  average 
monthly  rate  of  mean  seasonal  flow.  These  lines  sometimes  mount 
higher  and  higher  toward  the  tops  of  the  diaorarns  as  the  accumulated 
run-off  of  successive  above-normal  seasons  l)ecomes  greater  than  the 
simultaneous  accumulation  would  have  ])een  with  average  flow  all  the 
while.  At  other  times  they  turn  downward  and  during  series  of  below- 
normal  years,  approach  the  lower  margins.  In  pursuing  these'  flexural 
patlis.  the  sinuous  lines  cross  the  heavy  zero  lines  whenever  the  sum- 
mation of  run-off,  accumulated  since  the  first  year  of  the  diagrams, 
exactly  equals  the  accumulation  had  the  rate  of  run-off  always 
been  average;  and  this  may  occur  ou  either  upward  or  downwai'd 
inclinations. 


68  WATER   RESOURCES    OF    CALIFORNIA. 

To  give  values  to  these  departures  from  the  average  rates  of  stream 
flow,  the  plates  have  numbers  spread  along  their  margins.  The  upper 
margins  represent  time  and  the  fifty  equal  intervals  intercepted  by  the 
heavier  up-and-down  lines,  are  each  a  season  of  the  half  century  of 
run-off  portrayed  on  them.  The  years  of  the  successive  seasons  are 
printed  along  these  margins,  starting  from  the  left  border.  Also,  each 
seasonal  space  is  divided  into  three-month  periods  by  lightly  drawn 
up-and-down  lines.  The  side  margins  of  the  plates  have  numbers 
increasingly  large  as  they  extend  above  and  below  the  heavy  zero  lines 
which  cross  the  sheets.  In  multiples  of  ten,  one  for  each  equally 
spaced  cross  line,  these  numbers  denote  volumes  of  water  and  the  space 
between  their  lines  represents  ten  per  cent  of  the  mean  annual  flow  in 
the  streams. 

Beginning  at  the  left  in  the  first  of  the  fifty  years,  the  values  of  the 
successive  total  accumulations  of  water  were  plotted  month  by  month, 
and  the  sinuous  lines  of  the  diagrams  drawn  through  them.  These 
values  were  summed  progressively  while  expressed  for  each  month  in 
per  cent  of  the  mean  seasonal  run-off,  but  instead  of  retaining  the 
superfluously  cumbersome  number  one  hundred  in  the  summations  of 
these  percentages,  one-twelfth  of  it  was  subtracted  from  each  progres- 
sive monthly  sum.  Then,  the  actual  net  value  added  in  each  instance, 
was  the  departure  during  each  month  from  one-twelfth  of  the  mean 
seasonal  run-off  which  is  the  average  monthly  rate  of  flow  for  the  mean 
season.  This  mode  of  expressing  amounts  of  accumulating  waters  in 
percentage  values  of  their  departures  from  amounts  that  would  have 
accumulated  at  the  average  rate  of  flow,  is  a  technical  device  to  reduce 
labor  in  the  arduous  study  of  equalizing  the  periodic  stream  flow,  which 
would  otherwise  be  so  voluminous  in  figures  by  the  time  computations 
were  made  for  all  the  streams  of  the  state  and  for  every  desired  location 
on  each  stream,  that  years  of  labor  would  be  required  to  complete  it. 
The  artifice  in  effect,  so  reduces  the  size  of  plates  necessary  to  delineate 
the  mass  diagram.s  that  it  has  become  possible  to  print  them  in  this 
volume,  and  it  so  decreases  their  total  number,  that  only  one-sixth  as 
many  diagrams  had  to  be  drafted  as  would  have  been  necessary  if  the 
customary  method  of  technical  expression  had  been  employed. 

Plate  XIV,  "Construction  and  Interpretation  of  ]\Iass  Diagrams  of 
Run-oft',"  graphically  compares  the  diagram  of  accumulating  masses  of 
water  resulting  from  this  adopted  mode  of  expression,  to  the  form  of 
the  mass  diagram  of  customary  technical  procedure.  In  both  cases, 
however,  the  monthly  run-off'  is  expressed  in  per  cent  of  the  mean 
seasonal;  but  in  the  mass  diagram  of  usual  construction,  the  values  do 
not  have  the  one  hundred  per  cent  eliminated  from  the  sums,  so  that 
its  form  is  identical  to  the  ones  of  connnon  practice  which  are  con- 
structed in  standard  units  of  run-off"  such  as  the  acre-foot  or  gallon. 
The  plate  has  dimension  lines  and  figures  which  show  the  relation 
between  the  two  mass  diagrams  and  their  component  parts,  and  how 
they  wei'e  both  drafted  from  values  of  monthly  run-oft'  which  are  tabu- 
lated to  one  side  of  the  sheet.  Although  the  standard  diagram  is  not 
in  the  usual  unit  of  volume,  it  will  be  readily  recognized  as  custonuiry 
graphics  and  the  perusal  of  Plate  XIV  will  show  that  the  form  of  dia- 
gram used  in  these  investigatinns  is  identical  in  principle  to  the  usual 
form  and  difTers  from  it  only  in  mode  of  expression,  and  that  both 
may  be  employed  in  the  art  in  exactly  the  same  way.

WATER   RESOURCES    OF    CALIFORNIA.  69 

These  mass  diagrams,  Plates  XCV  to  CXLVIII,  in  expressing  the 
manner  of  occurrence  of  flow  in  all  the  streams  of  the  state  during 
the  past  fifty  years,  are  emblematic  of  its  irregularities  and  were  used 
to  determine  the  part  of  the  entire  flow  that  might  be  equalized  by  pro- 
viding various  volumes  of  storage  capacity  on  each  stream.  That  such 
uniform  equalization  might  be  attained  and  so  completely  that  it  would, 
without  question,  be  of  the  greatest  service  to  man,  waters  flowing  at 
irregular  intervals  were  not  included  in  that  part  of  the  stream  flow 
V  aich  was  regarded  as  equalized.  Instead,  with  the  storage  in  opera- 
tion, only  the  fraction  of  all  the  waters  in  the  streams  was  regarded  as 
equalized  that  would  have  passed  down  the  channels  apportioned 
among  the  months  of  the  year  in  accordance  with  irrigation  needs,  year 
after  year,  without  fail,  throughout  the  entire  fifty  seasons.  These  irri- 
gation needs  have  been  taken  from  Appendix  B^  of  this  report,  in  which 
the  seasonal  water  requirements  for  all  localities  of  the  state  have  been 
anportioned  among  the  months  of  the  year.  From  these  apportion- 
ments, expressed  in  per  cent  of  the  requirements  for  the  entire  season, 
five  typical  monthly  divisions  have  been  evolved.  These  were  selected 
so  that  the  needs  of  every  locality  are  closely  represented  by  one  of  the 
five  tvpes. 

Plate  CXLIX,  "Irrigation  Draft  Lines  for  Storage  Studies," 
presents  these  five  typical  monthly  divisions  of  the  total  seasonal  waters 
'^eded  for  irrigation.  They  are  expressed  as  drafts  or  demands  on 
the  streams  for  waters  to  supply  them.  For  each  one,  a  series  of  lines 
graphically  delineates  the  way  masses  of  water  would  accumulate  if 
the  rates  of  accumulation  were  always  adequate  to  supply  the'se 
demands.  Each  series  of  lines  is  labeled  with  one  of  the  letters  A  to 
E  and  thev  are  all  plotted  in  identical  units  and  to  the  same  scales  as 
plates  XCV  to  CXLVIII.  "Mass  Diagrams  of  Run-off."  The  several 
lines  in  each  series  represent  different  total  seasonal  drafts  but  have 
the  same  apportionment  of  water  among  the  months.  Since  the  total 
seasonal  drafts  are  always  less  than  the  average  stream  flow,  the  draft

WATER   RESOURCES    OF    CALIFORNIA.  69 

These  mass  diagrams,  Plates  XCV  to  CXLVIII,  in  expressing  the 
manner  of  occurrence  of  flow  in  all  the  streams  of  the  state  during 
the  past  fifty  years,  are  emblematic  of  its  irregularities  and  were  used 
to  determine  the  part  of  the  entire  flow  that  might  be  equalized  by  pro- 
viding various  volumes  of  storage  capacity  on  each  stream.  That  such 
uniform  equalization  might  be  attained  and  so  completely  that  it  would, 
without  question,  be  of  the  greatest  service  to  man,  waters  flowing  at 
irregular  intervals  were  not  included  in  that  part  of  the  stream  flow 
V  aich  was  regarded  as  equalized.  Instead,  with  the  storage  in  opera- 
tion, only  the  fraction  of  all  the  waters  in  the  streams  was  regarded  as 
equalized  that  would  have  passed  down  the  channels  apportioned 
among  the  months  of  the  year  in  accordance  with  irrigation  needs,  year 
after  year,  without  fail,  throughout  the  entire  fifty  seasons.  These  irri- 
gation needs  have  been  taken  from  Appendix  B^  of  this  report,  in  which 
the  seasonal  water  requirements  for  all  localities  of  the  state  have  been 
anportioned  among  the  months  of  the  year.  From  these  apportion- 
ments, expressed  in  per  cent  of  the  requirements  for  the  entire  season, 
five  typical  monthly  divisions  have  been  evolved.  These  were  selected 
so  that  the  needs  of  every  locality  are  closely  represented  by  one  of  the 
five  tvpes. 

Plate  CXLIX,  "Irrigation  Draft  Lines  for  Storage  Studies," 
presents  these  five  typical  monthly  divisions  of  the  total  seasonal  waters 
i.eded  for  irrigation.  They  are  expressed  as  drafts  or  demands  on 
the  streams  for  waters  to  supply  them.  For  each  one,  a  series  of  lines 
graphically  delineates  the  way  masses  of  water  would  accumulate  if 
the  rates  of  accumulation  were  always  adequate  to  supply  the^e 
demands.  Each  series  of  lines  is  labeled  with  one  of  the  letters  A  to 
E  and  thev  are  all  plotted  in  identical  units  and  to  the  same  scales  as 
plates  XCV  to  CXLVIII.  "Mass  Diagrams  of  Run-otf."  The  several 
lines  in  each  series  represent  different  total  seasonal  drafts  but  have 
the  same  apportionment  of  water  among  the  months.  Since  the  total 
seasonal  drafts  are  always  less  than  the  average  stream  flow,  the  draft 
lines  have  a  general  slope  downward  to  the  right  and  away  from  their 
zero  lines;  for  their  accumulating  masses  of  water  differ  by  ever 
increasing  amounts  from  the  simultaneous  accumulations  of  average 
stream  flow. 

The  draft  lines  were  successively  superimposed  on  the  mass  diagrams 
to  compare  them  with  the  various  sections  of  the  sinuous  lines  depict- 
ing run-off,  and  to  see  how  the  actual  manner  of  passing:  of  the  waters 
down  the  streams  is  like  the  manner  which  would  have  been  necessary 
to  put  portions  of  the  flow  to  complete  use.  Comparisons  were  made 
on  the  diagrams  of  every  stream  in  the  state  and  the  differences  noted 
between  the  erratic  orders  of  actual  stream  flow  and  the  uniform  orders 
of  flow  that  would  enable  complete  use  to  be  made  of  specific  portions 
of  their  waters.  In  these  comparisons,  only  one  series  of  draft  lines 
was  superimposed  on  the  diagram  of  each  stream  and  the  series  was 
used  which  has  a  monthly  division  of  the  seasonal  supply  most  nearly 
fitting  the  needs  of  the  areas  irrigable  from  that  stream. 

AVhen  placed  on  the  mass  diagrams,  the  draft  lines,  in  taking  more 
regular  courses  on  the  sheets,  intersect  the  windings  of  the  sinuous  lines 
representing  the  run-off.     The  distances  between  successive  points  of 

"Irrigation    requirement.s    of    California    lands. 


70  WATER    RESOURCES    OF    CALIFORNIA. 

intersection  of  these  two  lines,  referred  to  the  upper  margin  scales,  are 
the  periods  of  time  durinfj;  whii-h  total  run-off  and  total  drafts  are 
exactly  equal.  Tliat  the  two  lines  depart  from  each  other  between  the 
inter.section  points.  shoAvs  that  the  run-off  duriuju'  these  periods  of  equal 
totals  did  not  occur  at  the  draft  rates  but  at  other  rates  either  greater 
or  less.  When  greater,  the  sinuous  lines  of  run-off  climb  upward  above 
the  draft  lines  and  -when  less,  descend  toward  them.  The  departures  of 
these  two  lines  from  one  another  then  represent  total  volumes  of  water 
that  the  natural  regimen  of  the  streams  may  be  in  excess  of.  or  in  defi- 
ciency to,  the  total  drafts  since  the  beginning  of  the  period;  and  the 
maximum  departures,  when  tlie  run-off"  is  in  excess,  represent  the 
amounts  of  water  wliich  would  have  to  be  caught  in  storage  on  the  upper 
course  of  the  stream  and  released  later  for  augmenting  deficient  natural 
flows,  in  order  to  equalize  the  run-off  during  this  period  of  time  with 
complete  uniformity.  By  superimposing  the  draft  lines  on  the  mass 
diagrams  so  that  they  just  touch  the  sinuoiLS  lines  at  the  lowest  part  of 
their  long  downward  inclinations  to  the  right  where  they  are  about  to 
turn  upward,  the  draft  lines  intersect,  somewhere  oft'  to  the  left,  steep 
upward  inclinations  of  the  sinuous  lines.  The  periods  of  equal  total 
flow  and  draft  represented  by  the  space  between  these  two  intersections, 
then  close  at  times  when  the  stream  flow  is  changing  from  below  normal 
to  above  normal,  for  the  run-off  lines  ascend  upward  from  the  draft 
lines  for  distances  to  the  right.  The  equalization  of  stream  flow 
through  all  periods  which  have  sueh  closures,  completes  the  equalization 
for  the  entire  fifty  year.s  of  diagrannned  run-off'  except  for  occasional 
time  intervals  during  Avhich  the  run-oft'  was  greater  than  normal  and 
consequently  in  excess  of  the  draft  and  not  requiring  ecpialization. 

Plate  XIV.  "'Construction  and  Interpretation  of  Mass  Diagrams  of 
Run-off,"  shows  a  draft  line  superimposed  on  a  mass  diagram  of  run- 
oft'  so  that  it  is  just  tangent  at  one  of  these  lower  points  of  contra- 
flexure,  marked  "1).''  The  intersection  to  the  Jeft  is  marked  *'a." 
The  maximum  departure  of  the  run-off  line  from  the  draft  line  is 
labeled  "cd."  Then,  if  storage  capacity  in  the  amount  of  "cd"  to 
tlie  scale  of  the  drawing,  is  provided  on  the  stream,  the  flow  during 
the  period  of  time  "ab"  may  be  equalized  by  it  to  yield  the  uniform 
demand  represented  l)y  the  draft  line  which  is  superimposed  on  the 
mass  diagram.  iSinee  the  sinuous  line  turns  upward  to  the  right  at 
the  point  "b"  and  continues  above  the  draft  line  for  times  after,  the 
run-off  will  be  more  than  sufficient  to  su]iply  the  draft  following  the 
close  of  the  period  "ab. " 

Superimposing  in  this  way,  the  various  draft  lines  on  the  ina.ss 
diagrams  so  that  they  touch  the  sinuous  lines  at  all  the  lower  points 
of  contrartexure,  the  greatest  departures  between  their  intersections 
were  sealed.  The  largest  of  tlu^se  departures  for  all  trials  of  one  draft 
line,  was  recorded  as  the  storage  capacity  required  to  equalize  the  run- 
oft'  .sufficiently  to  yield  the  draft  according  to  the  line  used.  In  being 
adequate  to  equalize  tlie  flow  during  the  period  in  which  the  actual 
stream  flow  departed  most  widely  from  th(>  uniform  di-aft,  this  capacity 
would  be  more  than  M(le((uate  for  all  other  j^eriods  between  inters(M-tions 
and  so  thi'ough  its  oix-ratien.  would  make  i)ossible  without  fail,  a  uni- 
form draft  on  the  stream  throuuliout  the  entire  fifty  years  in  accord- 
ance with  the  rates  expressed  by  the  draft  line  wliieh  was  superimposed 
on  the  mass  diaszram. 


WATER   KESOURCES    OF    CALIFORNIA/  71 

The  findings  from  all  the  superimpositions,  made  in  this  way  for  all 
the  streams  and  for  all  rates  of  draft,  are  plotted  on  thirty-six  plates, 
CL  to  CLXXXV,  "Storage  Development  Curves."  On  them,  is  one 
diagram  for  each  stream  or  group  of  minor  streams  which  show  by 
curved  lines,  the  fractions  of  the  average  flow  in  the  streams  that  may 
he  equalized  by  constructing  storage  capacities  in  any  volumes.  The 
fractions  of  the  average  flow  are  expressed  in  per  cent  of  the  mean 
seasonal  run-ofiE  by  the  numbers  on  the  left  margins.  The  nund)ers  on 
the  upper  margins  express  the  storage  capacity  also  in  per  cent  of  the 
mean  seasonal  run-ofif.  The  valuer  on  these  two  scales  corresponding  to 
the  same  point  on  a  curve,  define  that  part  of  the  run-ofp  which  will  be 
made  available  for  irrigation  draft  in  uniformly  equalized  flow  by  con- 
struction of  the  storage  capacity  indicated  on  the  upper  margin. 

These  curves  are  seen  to  be  parabolic  in  shape  and  much  alike  for 
all  streams.  As  they  mount  upward  to  show  yields  of  larger  porti(ms 
of  the  total  run-off,  they  become  flatter  and  spread  out  more  to  the 
right  and  make  continually  greater  advances  in  the  direction  repre- 
senting greater  storage  for  each  unit  advance  on  the  run-off  scale.  The 
flatter  these  curv-es  become  as  thej'  approach  the  top  of  the  sheets,  the 
more  storage  capacity  must  be  provided  to  obtain  each  unit  increase 
in  equalized  flow.  On  the  streams  of  very  erratic  flow,  the  curves 
become  quite  flat  near  the  top ;  for  much  more  storage  capacity  must 
be  provided  to  hold  their  excess  waters  over  from  the  years  of  plenty 
to  those  of  need,  than  on  the  streams  with  a  steady  flow.  So  on  the 
steadier  streams,  the  curves  rise  the  more  directly  toward  the  top  of 
the  sheets. 

The  full  lines  on  the  diagrams  indicate  these  relations  taken  directly, 
from  the  mass  diagrams.  However,  evaporation  would  be  ever  active 
from  the  surfaces  of  the  reservoired  waters,  so  that  to  secure  the  net 
per  cent  of  run-off  that  would  be  available  for  use.  certain  deductions, 
must  be  made  from  it  for  losses  by  evaporation.  To  evaluate  these 
deductions,  the  average  area  of  surface  exposed  to  the  atmosphere  was 
determined  for  several  hundred  reservoirs  and,  from  statistics  on 
evaporation,  the  average  annual  loss  was  obtained  for  all  localities. 
Curves  of  dashed  lines  were  then  drafted  on  the  diagrams ;  these  fall 
below  the  full  line  curves.  The  ordinates  parallel  to  the  run-off  scale, 
which  are  intercepted  between  these  dashed  and  the  full  curves,  are 
the  values  of  these  evaporation  losses  from  the  reservoired  waters. 
The  storage  capacity  and  available  run-off,  disclosed  by  these  dashed 
curves,  are  then  the  ones  for  practical  use  for  they  show  the  net  quan- 
tities of  water  which  could  be  diverted  from  the  streams  for  irrigation 
use.  Both  the  storage  capacity  and  the  equalized  flow  made  availabln 
by  constructing  it.  are  in  terms  of  i)er  cent  of  the  mean  annual  run-off. 
To  evaluate  them  in  acre-feet,  the  per  cent  obtained  from  the  diagrams 
should  be  nudtiplied  by  the  nu^an  annual  run-otif  of  the  stream,  and 
this  is  ])rint('d  on  each  diagram.  Then,  these  one  hundred  and  forty 
storage  development  curves  set  forth  the  ((uantities  of  water  made 
available  for  irrigation  use  through  the  con.struction  of  any  volume  of 
storage  that  might  be  desired  on  California's  streams.

CHAPTER  VII. 


WATER  RESOURCES  OF  THE  STATE. 

Only  one-half  of  the  wide  expanse  of  California  eontributes  to  the 
waters  of  its  streams.  The  other  half,  lower  in  altitude  and  more  even 
of  surface,  is  favorably  disposed  for  the  oceupancy  of  man,  and  its 
populated  sections  need  water  in  order  that  their  industrial  expansion 
may  continue  and  communal  civilization  progress  steadily  onward.  The 
production  of  food,  the  generation  of  power,  and  the  supply  of  water  for 
domestic  use,  in  the  drier  half  of  the  state,  are  largely  dependent  upon 
the  waters  of  the  streams  ^vhich  have  their  source  in  the  more  elevated 
regions.  The  farmer  relies  upon  the  streams  during  the  warm,  dry  sum- 
mers for  supplementary  moisture  to  mature  his  crops  and  upon  their 
hydro-electric  energy  to  pump  his  irrigation  waters.  The  electric 
energy,  generated  by  the  waters  of  the  streams  as  they  descend  the 
mountain's  slopes,  furnishes  power  and  illumination  to  the  industrial 
centers,  and  light  and  heat  and  means  of  operating  many  conveniences, 
to  the  entire  social  organization.  But  most  of  all,  the  cities,  towns,  and 
villages,  the  pleasures  and  comforts  of  their  congregated  people,  require 
these  waters  in  abundance  for  drinking  and  washing  purposes,  and  the 
expansion  of  all  these  benefits  to  include  larger  populations,  demands 
increased  supplies  for  the  future  and  the  uninterrupted  service  of  water 
in  purity  and  plenty,  at  all  times  of  the  year,  and  in  all  successive  years 
alike. 

However,  California's  waters,  fluctuating  in  amount  not  alone 
throughout  the  year,  but  markedly  from  one  yi^ar  to  anothei-,  drain  otf 
its  mountain  lands  in  concentrated  winter  floods  or  in  dwindling  and 
meager  summer  flows.  This  erratic  behavior  of  the  state's  streams, 
whereby  their  courses  are  intermittently  deluged  by  rising  floods  or 
emptied  by  vanishing  waters,  necessitates  that  their  regimen  be  recti- 
fied if  man  is  to  utilize  their  powers  in  aecelcrating  his  advancement. 
The  capricious  irregularity  of  natural  flow  has  to  )h'  e(|uali/,ed  to  make 
waters  available  at  the  times  and  in  tlie  (|uantitit's  needid. 

To  discern  the  reliable  amounts  whieh  may  be  iiuulf  ;ivailal)l('  liy 
equalizing  these  variable  supplies,  as  well  as  to  discover  tlic  most  favor- 
able sources  from  whieh  waters  may  be  transported,  aiv  eciually  impor- 
tant in  planning  works  to  accomplish  man's  desires.  For  these  pui-- 
poses,  it  is  imperative  that  full  knowledge  be  gained  of  the  location  of 
the  state's  waters,  their  amounts,  and  the  variability  of  their  produc- 
tion. That  these  features  might  l)e  i-evealed  Tal)le  :5,'"  Water  Resources 
of  California,"  lists  hydrographic  (piantities  concerning  every  stream  of 
the  state.  In  this  table,  one  hundred  forty  streauLs  or  groups  of 
minor  .streams  are  arranged  in  geographic  order  and  segregated  by  the 
six  large  topogi'aphic  divisions  of  the  state:  the  basins  of  the  Sacramento 
and  San  Joaquin ;  and  the  regions  of  San  Francisco  Bay,  of  the  north 
and  south  Pacific  coasts,  and  of  the  Great  Basin.  The  location  of  each 
one  of  these  streams  or  groups  of  minor  streams,  is  sliown  on  tlie  map  of 
California,  Plate  XV,  "Map  Showing  lioundaries  of  Drainage  Basins."

WATER    RESOURCES    OP   CALIFORNIA.  73 

The  features  of  all  these  streams,  the  amounts  of  their  waters,  and 
the  variability  of  their  production,  are  characterized  in  Table  8,  by 
values  listed  in  forty  columns  extending  out  to  the  right  from  the  first 
two,  which  contain  their  names  and  reference  numbers.  Through  these 
reference  numbers,  information  may  be  traced  in  the  diagrams  and 
tables  of  the  previous  chapters,  which  is  too  voluminous  to  incorporate 
in  this  summary  tabulation.  The  values  which  are  listed  in  the  forty 
columns,  all  concern  the  run-off  from  the  drainage  areas  lying  upstream 
from  the  main  bodies  of  agricultural  land  along  their  lower  reaches. 
The  areas  of  these  drainage  basins  are  printed  in  the  third  column  and 
in  the  fourth  to  the  twelfth  are  values  of  their  run-off  expressed  in 
several  different  units.  These  entries  include  the  quantity  of  water 
running  off  their  collecting  areas  in  an  average  season,  and  also  in  the 
seasons  of  greatest  and  least  run-oft".  The  quantities  affixed  to  each 
stream,  definitely  locate  all  the  state's  waters  and  show  between  what 
limits  the  flow  of  sucessive  seasons  may  vary.  The  mean  seasonal 
quantities  express  the  average  amounts  in  which  they  may  be  expected 
to  appear  and  constitute  a  statement  of  all  existent  waters. 

While  the  average  annual  water  production  of  all  these  streams  is 
72,500,000  acre-feet,  this  invoice  of  California's  waters  shows  that  the 
maximum  yield  is  two  and  three-quarters  times  this  amount,  and  that 
the  least  season's  yield  is  but  three-eighths  as  much.  The  total  run-oft' 
in  successive  seasons,  then,  fluctuates  between  limits,  one  seven  times 
the  other,  and  the  value  of  any  one  season  lies  at  random  between  them. 

In  addition  to  changing  from  year  to  year,  all  the  streams  of  the  state 
have  a  fluctuating  daily  flow.  Inclusions  have  been  made  in  columns 
13  to  18,  and  35  to  42,  of  Table  3,  to  define  the  extremes  between  which 
the  daily  flows  are  accustomed  to  range.  Columns  13  to  18  give  vahies 
to  the  run-oft'  during  the  months  of  July  and  August.  These  two  mid- 
summer months  are  times  of  the  year  of  nearly  the  least  flow  and  in 
which  water  is  of  much  value  agriculturally.  The  quantities  include 
the  entire  month's  run-off,  and  when  divided  by  sixty,  afford  values  of 
the  average  daily  flow  during  the  low  water  periods  in  cubic  feet  per 
second.  Contrasting  them,  are  the  values  of  flood  flows  in  columns  35  to 
42.  These  entries  are  of  especial  import  in  not  only  indicating  the 
upper  limits  of  variability  in  stream  flow,  but  also  in  indicating  the 
maximum  volumes  of  water  which  flood  i)rotection  works  may  have  to 
withstand.  (Comparisons  of  these  flood  values  with  the  low  water  flows 
of  July  and  August,  disclose  a  surprisingly  great  range  in  the  rate  of 
fiow  in  California's  streams. 

As  an  average  over  the  whole  state,  the  greatest  daily  flow  exceeds 
five  hundred  times  the  lea«t.  In  taking  values  between  these  wide  limits 
for  all  the  days  of  successive  years,  the  greater  flows  exceed  the  least  in 
all  degrees  of  magnitude.  ])ut  the  very  large  ones  are  the  most  infre- 
quent in  occuri-ence.  To  give  pei-si)e('tive  to  the  occurring  fre(|uency  of 
exceedingly  great  flows,  the  sizes  that  may  be  surpassed  within  intervals 
of  tweiity-five,  fifty,  seventy-five,  and  one  hundred  years,  are  tabulated 
in  columns  35  to  42.  These  greatest  values  of  mean  daily  flow  constitute 
the  floods  of  California's  streams  and  it  is  to  ])e  observed  in  general,  that 
once  in  twenty-five  years  the  extraordinary  values  of  daily  flow  swell 
at  least  forty-fold,  the  average  volume  in  their  channels;  and  that  once 
in  one  hundred  years,  even  these  may  be  exceeded  by  flows  that  are 
one-quarter  larger. 


lA  WATER   RESOURCES    OF    CALIFORNIA. 

So  large  are  the  volumes  of  water  that  pass  down  the  state's  water- 
ways during  these  great  floods,  that  the  rate,  which  would  only  be 
exceeded  on  an  average  of  four  times  a  century,  would  send  a  plethora 
of  waters  into  the  ocean  within  four  daj's  whose  aggregate  is  equiva- 
lent to  the  entire  production  of  every  drainage  basin  in  the  state  for 
their  seasons  of  least  flow.  During  but  one  of  these  days,  tlie  total  flow 
wouhl  be  ample  to  supply  an  urban  population  of  seventy  millions  of 
l)eople  with  domestic  water  for  a  3'^ear,  or  to  irrigate  four  million  acres 
of  agricultural  land  through  an  entire  season,  or  still,  to  generate  one 
hundred  thousand  horsepower  continuously  for  twelve  months  when 
dropping  through  a  height  of  one  hundred  feet.  Nevertheless,  these 
volumes  of  water  are  useless  to  man  because  of  their  extremely  infre- 
quent appearance  in  the  stream  channels.  The  Avaters  of  lesser  floods, 
however,  may  be  caught  by  storage  works  constructed  in  the  moun- 
tainous regions  and  be  detained  for  later  release  to  supplement  the 
wailing  natural  flow  in  the  streams.  By  such  detention  of  the  flood 
Avaters  for  subsequent  use,  the  erratic  run-ofl'  may  be  equalized  and 
made  available  to  man  at  times  convenient  to  his  special  p^urposes. 

The  greatest  fractions  of  the  mean  seasonal  floAv  Avhieh  may  be  con- 
strained to  man's  service  through  retention  in  storage  reservoirs,  are 
set  forth  for  all  the  streams,  in  column  20  of  Table  3,  and  in  colnmn 
21  are  found  the  storage  capacities  required  to  do  this.  The  yields  from 
lesser  amounts  of  storage  are  giA^en  in  columns  23  to  34.  The  maximum 
yield  possible  from  the  entire  Avater-producing  areas  of  the  state  is 
58,300,000  acre-feet  annually,  or  80  per  cent  of  the  mean  seasonal  run- 
off. To  secure  this  maximum  yield  Avould  require  storage  of  184,900.000 
acre-feet  total  capacity.  This  volume  is  slightly  greater  than  three 
times  the  annual  equalized  yield.  Such  large  proportional  amounts  of 
storage  are  not  needed  if  smaller  fractions  only,  of  the  mean  sea.sonal 
floAV  are  eipialized.  Capacity  for  storage  of  two  times  the  net  aiuiual 
yield,  will  develop  70  per  cent  of  the  mean  annual  run-off  from  the 
state's  drainage  areas,  and  Avhen  this  eai>acity  is  just  equal  to  tiu^  yield 
in  volume,  it  Avill  develop  40  per  cent  of  the  mean  annual  run-oft'. 

All  these  hydrographic  quantities  of  Table  3,  Avhile  having  character- 
istics which  qualify  the  state's  waters  as  a  Avhole,  vary  considerably  for 
the  separate  drainage  basins.  Nevertheless,  adjacent  basins  are  .suffi- 
ciently alike  to  render  distinction  to  Avhole  regions  by  reasons  of  their 
special  values.  These  regional  values,  in  d<q)arting  from  those  for  tlie 
entire  state,  are  still  only  indicatiA'c  of  the  predominating  characteristics 
of  th(!  region,  and  individual  basins  nuiy  have  features  widely  ditferent 
from  the  predominant  ones. 

The  six  large  top()gra])!iic  divisiojis  of  the  state  liavt^  s\ich  ]>i'edomi- 
uant  regional  charactei-istics.  Of  the.se,  tlie  Sacramento  Drainage  Basin 
is  the  lai-gest.  It  comprises  not  only  all  the  area  lying  betAveen  the 
(.'oast  Range  and  Sierra  Nevada  mountains  -as  far  south  as  Suisun  Bay, 
but  also  the  drainage  area  of  Pit  River  to  the  east  of  tiu^  mountains  in 
the  northeastern  corner  of  the  state.  This  large  basin  contfMns  one- 
(|uartei'  of  the  state's  water-produciny  area,  and  Avith  the  exception  of 
the  noi-th  Paciflc  Coast  regio)i,  it  ])roduces  more  than  an_\-  other  of  the 
six  divisions  and  one-third  of  all  Califoi'jiia 's  watei's. 

The  San  Joaiiuin  drainage  basin  is  second  largest  of  the  six  topo- 
graphic  divisions,   but  only   produces  one-sixth   of  tlu^  Avaters.     This 


WATER   RESOURCES    OF    CALIFORNIA.  75 

basiii  comprises  all  the  area  between  the  Coast  Range  and  Sierra  Nevada 
mountains,  southerly  from  Suisun  Ba.v  to  Tehachapi  Pass.  The  third 
largest  division  is  the  north  Pacific  Coast  region  which  includes  all  the 
streams  draining  into  the  Pacific  Ocean  northward  from  San  Francisco 
Bay.  It  contains  only  one-fifth  of  the  water-protlucing  area,  but  over 
one-third  of  all  the  water.s  of  the  state  run  off  its  drainage  area.  This  is 
a  greater  yield  than  in  any  other  of  the  tlivisions.  For  e<iual  area,  it 
produces  one-third  more  water  than  the  Sacramento  Basin  and  over 
twice  that  of  the  San  Joa(iuin.  This  region  contains  the  most  produc- 
tive drainage  basin  in  the  state,  the  Smith  River.  Although  it  is  only 
627  square  miles  in  extent,  the  mean  annual  I'un-off  is  nearly  three 
and  one-half  million  acre-feet. 

The  region  southward  from  San  Francisco  Bay  which  drains  into 
the  Pacific  Ocean,  is  called  the  south  Pacific  Basin  and  is  the  region 
of  smallest  water  yield.  Although  containing  one-sixth  of  the  drainage 
area,  but  one-twentieth  of  the  state's  waters  run  off  its  slopes.  Next  in 
size,  is  the  region  of  the  CTreat  Basin  which  comprises'  the  areas  easterly 
from  California's  principal  mountain  system,  and  whose  waters  do  not 
reach  the  ocean.  One-tenth  the  water-producing  area  of  the  state  is  in 
this  region  but  it  yields  only  one-twentieth  of  the  waters;  its  increment 
is  about  equal  to  that  of  the  South  Pacific  region.  The  smallest  of  the 
six  topographic  divisions  is  the  area  draining  into  San  Francisco  Bay 
which  contributes  only  one  per  cent  to  the  total  waters  of  the  state. 

There  is  a  great  difference  between  these  six  regions  in  the  manner 
in  which  their  waters  run  off  the  collecting  areas.  Generally,  the 
regions  of  least  total  production  have  the  greatest  variability  in  run-off 
and  demand  more  capacity  in  storage  works  to  equalize  their  stream 
flow.  The  south  Pacific  region,  the  least  productive  of  the  six,  requires 
three  times  the  capacity  necessary  on  the  Sacramento  and  San  Joaquin 
.streams,  to  obtain  equal  effects.  The  north  Pacific  region,  the  most 
productive  of  the  six,  requires  slightly  more  storage  than  in  the  Sacra- 
mento and  San  Joaquin  basins  since  it  has  a  smaller  summer  flow  in  its 
streams.  The  San  Francisco  Bay  region  has  the  least  summer  flow  of 
the  six  divisions,  but,  having  a  smaller  annual  fluctuation  than  the  south 
Pacific  region,  it  falls  intermediate  in  the  effectiveness  of  storage  on  its 
streams,  between  the  south  Pacific  region  and  the  three  largest  water- 
producing  regions  for  whicli  storage  capacity  is  nearly  equally  effective. 
Almost  twice  as  much  capacity  is  required  to  gain  eriual  results  in  the 
San  Francisco  Bay  region  as  on  the  Sacramento  and  San  Joaquin 
rivers. 

The  amounts  of  storage  required  to  eciualize  the  flow,  relate  largely 
to  the  variation  between  years  of  maximum  and  minimum  runoff  and  to 
the  apportionment  of  the  annual  run-off  between  the  winter  and 
summer  months.  The  North  Pacific  region  has  the  smallest  variation  in 
annual  run-off,  and  there  the  maximum  is  only  five  times  that  of  the 
minimum  season.  The  maximum  year  in  the  Sacramento  Basin  is  six 
times  the  least,  while  in  all  the  other  regions  the  variation  is  much  larger 
than  in  these  two :  in  the  San  Joaquin  it  is  fifteen  times  the  least,  in  the 
San  Francisco  Bay  region  it  is  seventy  times  the  least,  and  in  the  south 
Pacific,  the  year  of  maxim'um  run-off  is  one  luuidred  times  the  least 
year.  AVhile  the  San.  Francisco  Bay  region  has  the  smallest  portion 
of  its  waters  wetting  the  stream  channels  during  the  summer  months, 


76  WATER   RESOURCES    OF    CALIFORNIA. 

the  Great  Basin  drainage  is  distinguished  by  having  the  largest  appor- 
tionment of  summer  flow  of  any  of  the  six  regions.  The  streams  of  the 
San  Joaquin  Basin  are  next  in  order  and  those  of  the  Sacramento  not 
far  behind.  The  north  Pacific  region  has  an  intermediate  apportion- 
ment in  the  summer  months  between  tliat  of  the  San  Joafjuin  and  that 
of  the  South  Pacific  region. 

Similar  comparisons  may  be  made  between  any  of  the  individual 
drainage  basins  in  the  state  by  entering  Table  3  in  the  proper  columns. 
The  flow  in  all  streams  during  the  largest,  the  smallest,  and  the  average 
season,  as  well  as  during  the  midsummer  months,  is  there.  Also  the 
storage  capacity  required  to  equalize  their  variant  flows  and  the  size 
of  extreme  floods  are  enumerated.  So,  comprised  within  Table  3,  is  a 
complete  inventory  of  all  the  waters  of  the  state  wliich  includes  their 
locations,  their  quantities,  and  their  variabilities.  The  values  entered 
in  the  table  are  averages  for  the  past  half  century  and  should  be  indica- 
tive of  future  expectancies,  so  that  this  table  presents  in  full  the  water 
resources  of  the  State  of  California  with  their  characterizations.

TABLE  4.     RAINFALL  STATIONS  AND  SUMMARY 
OF  PRECIPITATION  DATA. 


This  table  presents,  in  alphabetical  order,  the  rainfall  stations  of  the 
United  States  Weather  Bureau  which  have  records  of  precipitation  cov- 
ering periods  of  ten  years  or  longer. 

The  reference  numbers  appearing  in  the  first  column  identify  the  sta- 
tions n  Tables  2  to  31,  inclusive,  and  on  Plates  II  to  XII,  inclusive, 
and  XVII.  The  stations  are  listed  in  numerical  order  on  Plates  XII  and 
XVII. 

The  table  number  in  column  four  refers  to  Tables  2  to  30,  inclusive, 
Records  of  Precipitation  and  Table  of  Computed  Indices  of  Wetness, 
and  Table  31,  Miscellaneous  Precipitation  Records  of  U.  S.  Weather 
Bureau.  These  tables  present  the  measured  seasonal  precipitation  at 
the  stations  listed,  and  the  computed  index  of  seasonal  wetness  for  each 
season  of  the  50-year  period  from  1871-72  to  1920-21. 

In  column  five  is  given  the  designating  letter  of  the  precipitation 
division  in  which  the  respective  stations  are  located,  the  boundaries  of 
which  are  shown  on  Plate  XII,  IVIap  Showing  Boundaries  of  Precipita- 
tion Divisions. 

In  column  eight  is  presented  the  mean  precipitation  for  the  50-year 
period  for  the  respective  stations.  This  value  is  computed  for  those 
stations  having  less  than  fifty  years  of  record.

WATER   RESOURCES    OP    CALIFORNIA.  157 

TABLE  32.     DRAINAGE  AREAS  IN  CALIFORNIA. 

The  area  in  square  miles  of  all  water-producing  drainage  basins  in 
California,  is  given  in  this  table.  Determinations  were  made  from 
topographic  maps  of  United  States  Geological  Survey  by  planimeter  and 
checked  in  their  totals  to  computed  areas  between  meridians  and  parallels 
of  latitude.  For  areas  not  mapped  by  the  United  States  Geological 
Survey,  the  maps  of  the  United  States  Forest  Service  and  various  state 
and  county  maps  were  used. 

All  streams  are  grouped  in  geographic  order  within  the  six  divisions 
of  the  State : 

Sacramento  Basin. 

San  Joaquin  Basin. 

San  Francisco  Bay  Basin. 

North  Pacific  Basins. 

South  Pacific  Basins. 

Great  Basin. 
The  one  hundred  and  forty  major  streams  or  groups  of  smaller  streams 
used  in  developing  run-off  curves  (Plates  XVIII  to  LIII,  inclusive),  in 
this  report,  are  listed  to  the  extreme  left  in  the  table  and  above  each 
name  are  listed,  indented  to  the  right,  the  tributaries  and  the  drainage 
area  of  each.  Branches  of  the  tributaries  are  listed,  with  their  drainage 
areas,  indented  still  further  to  the  right,  and  above  the  name  of  the 
tributary.  All  branches  and  tributaries  are  listed  in  order  of  their  con- 
fluence beginning  at  the  headwaters  and  the  areas  are  measured  to  the 
points  of  confluence.  Tables  Nos.  34  to  173,  inclusive,  describe  specific- 
ally the  lower  limit  of  the  areas  on  the  main  streams  which  are  measured 
to  the  head  of  the  main  agricultural  area. 

The  word  "Direct"  is  used  in  this  table  referring  to  the  area  draining 
directly  into  the  streams  between  points  of  confluence  of  branches  o 
tributaries  or  between  a  point  of  confluence  and  the  lower  limit  to  which 
the  drainage  area  was  measured.

(a)  Description  of  drainage  basin:  North  Honcut  Creek,  one  mile  above  junction  with  South  Honcut  Creek,  63.6 
square  miles;  South  Honcut  Creek,  including  Prairie  Creek,  one  mile  above  junction  with  North  Honcut  Creek,  87.2

North  Honcut  Creek,  27.5  square  miles;  Dry  Creek,  500  feet  above  junction  with  Yuba  River,  105.9  miles. 

(b)  The  distribution  of  seasonal  run-off  by  months  was  estimated  as  follows:  The  means  of  record  of  rainfall  by 
months  and  seasons  for  three  nearby  rainfall  stations,  Colgate,  Dobbins  and  Palermo,  were  averaged,  50%  of  rainfall 
for  each  month  was  carried  into  next  following  month,  and  the  resulting  values  were  reduced  to  percentages  of  the  mean 
seasonal  rainfall,  which  are  assumed  to  represent  the  monthly  distribution  of  run-off
